I originally posted this post on my blog a long time ago in a galaxy far, far away. Want to be ignored on Slack or Teams at work? Type "Hello, how are you?" and press enter. You'll get ignored immediately. Especially if you're working in a remote team with people all over the world. And especially if you're reaching out to a busy manager or executive. Hello, how are you? ... Good, thanks. And you? ... Good too, thanks. Hey, I just wanted... But, what if your recipient is on the other side of the world? 24 hours could pass between each message. And for sure, you don't want to wait 48 hours to start the real conversation. While working remotely at a past job, I used nohello.net as my Slack status. That page shows a fake "hello, how are you?" conversation, getting ignored. And I still got "Hello, how are you?" messages. Arrrggg! I know you wouldn't. Then, why do the same on Slack or Teams at work? Next time you want to reach out to someone at work: Don't just send "Hello, how are you?" Say hi and in the same message, without waiting for an answer, say what you really want to say. Let me say that again, in the same message, without waiting for an answer. That should be "Remote Working 101" when onboarding new team members at any remote company. Starting out or already on the software engineering journey?

Introduction In software development, especially when dealing with APIs, it’s crucial to have data accurately represented according to the expected formats. In this case, you're working with gRPC and need to customize how bytes fields are marshaled to JSON. If your application exchanges data including SHA-1, SHA-256, and UUIDs as bytes, you might find the default behavior of converting bytes to base64 rather limiting. Let’s explore how to implement a custom marshaler in Go to handle this effectively, ensuring that your specific use case can accommodate hexadecimal encoding instead of base64. Why This Issue Occurs The default behavior for handling bytes in gRPC-Gateway is to convert them into base64 later when transforming them into JSON. This decision can be frustrating when hexadecimal re…  ( 5 min )

One major feature of Javascript is it is a single-threaded environment; it can only execute one task at a time. When one function calls another, the JavaScript engine carefully tracks these calls using a mechanism known as the "call stack."; A data structure that follows the LIFO (Last In, First Out) principle, a function call is added (pushed) to the top of this stack. When the function, and removed (popped) from the stack when the function completes its execution. Imagine the call stack as a tower of tasks, where each new function call adds another level to the tower. function greet() { console.log("Hello!"); sayName(); console.log("Goodbye!"); } function sayName() { console.log("Ny name is David."); } greet(); When this code runs, the engine first places greet() on the call s…  ( 7 min )

Amazon ECS (Elastic Container Service) has just rolled out support for Amazon EBS Provisioned Rate for Volume Initialization — a powerful feature that speeds up EBS volume readiness when attaching from snapshots. This update is a game-changer for ECS workloads like: 🧪 ETL pipelines 🎞️ Media transcoding 🤖 Machine Learning inference With this enhancement, ECS tasks and services on both Fargate and EC2 launch types can now attach fully-performant EBS volumes right from the get-go! Previously, you could initialize ECS task volumes from EBS snapshots using snapshot-id, but performance was not guaranteed right away — data restoration from the snapshot could slow things down. Now, with Provisioned Rate for Volume Initialization, you can: ✅ Specify the initialization rate when creating volumes from snapshots In real-world production scenarios, time is money: ⏱️ ETL jobs don’t wait — they need volumes ready instantly 📺 Media processing workloads are time-sensitive 📦 ML inference needs low-latency, high-throughput disk access By provisioning initialization rates, you reduce startup delays and ensure consistent performance across containers. Define EBS volume attributes (size, type, IOPS, throughput). Attach volume to ECS task using a snapshot (snapshot-id). Specify the initialization rate during provisioning. ECS ensures attached volumes are fully-performant on task launch. ✅ Amazon ECS on Fargate ✅ Amazon ECS on EC2 ✅ ECS Tasks and Services You can also set this rate in ECS Task Definitions or Service Configurations, making it easy to standardize performance across deployments. This update from AWS bridges the gap between fast EBS volume access and containerized workloads. If you’re building data-intensive, high-performance applications on ECS, it’s time to take advantage of predictable storage performance with Provisioned Rate Volume Initialization.  ( 4 min )

Introduction Creating a user-friendly interface is essential in any application. When working with SwiftUI, you may want to enhance the usability of forms, particularly in a macOS application. In this guide, we will explore how to modify a grouped-styled Form to make a button that spans the entire row, allowing for smoother interaction. Our example involves managing a list of names, where we want the "New Person" button to be fully clickable, similar to List buttons in iOS. Understanding the Issue In SwiftUI, when you use a basic Button within a Form, it might not visually match the expected behavior found in List. Users often expect a row to be clickable throughout, not just the button area. To achieve a consistent feel with the functionality provided by NavigationLink, we need to use an …  ( 4 min )

Introduction If you're working with TypeScript, you might encounter a situation where you want to convert a union type into an enum for better organization and type safety. This is a common challenge, especially when trying to improve the maintainability of your code. In this article, we will illustrate how to achieve this conversion using clear examples. Understanding Union Types in TypeScript Union types in TypeScript allow you to define a variable that can hold one of several types. For example, consider the union type status: type status = 'start' | 'loading' | 'stop'; This means that any variable of type status can only be assigned one of those three string values: 'start', 'loading', or 'stop'. However, using union types can sometimes lead to a lack of organization, especially in la…  ( 4 min )

The function we’ll discuss, foo, uses assertions to catch errors during development but ensures backward compatibility by returning null for unexpected values in production. Here’s the function: int? foo(int value) { if (value 5) { return null; // null is returned in some non-error cases } retu…  ( 5 min )

If you're new to containerization or just want a clear understanding of Docker, you're in the right place. In this post, we’ll walk through the what, why, and how of Docker in a simple, no-fluff format. 📦 What is Docker? Docker is an open-source platform that makes it easier to build, ship, and run applications using containers. A container is a lightweight, portable package that includes everything your app needs to run: source code, libraries, dependencies, and environment variables — all bundled together. Think of it like a “super zip file” that runs your code the same way on any machine. 🤔 Why Was Docker Needed? Before Docker, developers faced the classic: "It works on my machine" 😤 Apps would break when moving between dev, test, and prod environments due to OS differences, miss…  ( 4 min )

Let’s talk about something that’s been bugging me for years: the disconnect between how we design APIs and how we manage data. We throw around phrases like “API-first” and “decoupled architecture” like they’re magic spells. And yeah—they’re important. But too often, API-first ends up being endpoint-first... and model-later (or never). That’s a problem. A big one. 🎯 The Problem with Endpoint-First Thinking I’ve been on projects where we had beautifully documented APIs. Swagger UI, OpenAPI specs, even good versioning. But behind the scenes? No consistency across services Fields named three different ways depending on the team No central data structure—just whatever someone came up with on the fly Eventually, we were duct-taping together integrations and trying to reverse-engineer payloa…  ( 4 min )

I’ll walk through the process of adding this MCP server and some of the risks we will want to think about. Here are the official instructions from GitHub- https://github.com/github/github-mcp-server. I ended up using the manual install option and choosing to run it in Docker. You’ll go into user preferences and add this into Preferences: Open User Settings (JSON), replacing the personal access token with your own. { "mcp": { "inputs": [ { "type": "promptString", "id": "github_token", "description": "GitHub Personal Access Token",…  ( 5 min )

When porting a website to HTML, you might encounter issues when your JavaScript tries to access files like a web manifest and is blocked by CORS policies. If you're in a situation where you have the data for manifest.webmanifest, you may wonder how to incorporate that data directly into your JavaScript without the need for an external file. Let's explore the reasons behind CORS restrictions and provide step-by-step solutions to embed the manifest data. Understanding CORS and Its Impact CORS, or Cross-Origin Resource Sharing, is a security feature implemented by browsers that restricts web pages from making requests to a different domain than the one that served the web page. This helps prevent malicious actions but can be a hurdle during local development or when porting sites. If you're f…  ( 4 min )

1. Intro: Why Go Concurrency Primitives Matter Go’s concurrency model is a developer’s dream—goroutines and channels make parallel programming feel effortless. But in the real world, they’re not always enough. Enter the sync package: a toolkit of concurrency primitives like Mutex, RWMutex, WaitGroup, and sync.Pool that can turbocharge performance or save you from subtle bugs. If you’ve got 1-2 years of Go under your belt, you’re probably comfy with goroutines and channels. But when faced with a high-traffic web server or a tricky task scheduler, questions creep in: Should I use Mutex or RWMutex? Does sync.Pool really help? Pick wrong, and your app’s performance tanks. In this guide, we’ll break down these primitives with benchmarks, real-world tips, and a handy selection cheat sheet. I’l…  ( 7 min )

Ever try to monitor a laser system in real-time... with Excel? Yeah, I’ve been there. A couple years ago, I was asked to build a dashboard for a medspa’s laser lipo machine. They wanted live data. Not just logging—but pulse-by-pulse, second-by-second monitoring. My first thought? “This is gonna be a nightmare.” You’d think there’d be some ready-made solution, especially in places as tech-savvy as a Medspa in Chicago. But nope. At first, we tried to jury-rig a CSV parser that pulled in log files every 10 minutes. Huge mistake. We missed surges in energy output, and one day the machine overheated mid-session. That’s when it hit me: we needed true real-time telemetry. Enter: Node.js (or Python, if that’s your jam). Here’s the quick-and-dirty framework I came up with: Stream the machine’s da…  ( 4 min )

A dynamic list updates based on user actions like adding, removing, or editing items. In this tutorial, you'll learn how to create a dynamic list using HTML, CSS, and JavaScript. Basic knowledge of HTML, CSS, and JavaScript A code editor (like VS Code) A browser for testing Create a basic HTML file: Dynamic List ul { padding-left: 20px; } li { margin-bottom: 5px; } button { margin-left: 10px; } Dynamic List Add Create a file named script.js and add the following code: function addItem() { const input = document.getElementById('itemInput'); const value = input.value.trim(); if (value === '') return; const li = document.createElement('li'); li.textContent = value; const removeBtn = document.createElement('button'); removeBtn.textContent = 'Remove'; removeBtn.onclick = function () { li.remove(); }; li.appendChild(removeBtn); document.getElementById('itemList').appendChild(li); input.value = ''; input.focus(); } How It Works? The user types a value in the input field. When the Add button is clicked, addItem() runs. It creates a new with the input text and a "Remove" button. Clicking "Remove" deletes that item. Here is the full example in JSFiddle. You now have a simple dynamic list using JavaScript. You can improve it by saving items to localStorage, adding edit buttons, or using frameworks like React for complex UIs.  ( 3 min )

When performing arithmetic with unsigned types in C++, especially with types like std::uint8_t, it's common to encounter questions surrounding modular arithmetic behavior. Specifically, many developers wonder if they can detect when a subtraction operation underflows (i.e., wraps around) without explicitly comparing the two operands. Understanding Subtraction with Unsigned Types In C++, when subtracting one unsigned integer from another, the result is constrained within the limits of the type. For std::uint8_t, this means that values wrap around when the result would go below zero. For example, subtracting 5 from 3 results in 254 due to the wrapping behavior inherent in unsigned types. To validate whether an underflow occurred during subtraction, comparisons are typically used. However, th…  ( 5 min )

Introduction In ASP.NET Web API, retrieving the IP address of a remote host making a request can be crucial for various scenarios, such as logging, security checks, and analytics. While ASP.NET provides the System.Web.HttpRequest class with a ServerVariables property to access the REMOTE_ADDR variable for obtaining the client's IP address, achieving this in ASP.NET Web API is slightly different. This article will explore how you can effectively get the IP address of the remote host in an ASP.NET Web API application. Understanding the HTTP Context In ASP.NET Web API, unlike traditional ASP.NET applications, the context is represented by a different class. You'll work with HttpRequestMessage to obtain the information you need, including headers that can contain details regarding the client's…  ( 4 min )

Abstract This paper introduces SMUGGLER, a novel neural architecture for direct byte-level text generation with remarkable efficiency and error tolerance. Unlike conventional token-based language models, SMUGGLER operates on raw 32-bit character chunks using three innovative mechanisms: 1) Temperature-controlled sparse voter ensembles, 2) Prime-numbered multi-channel parity correction, and 3) RLHF-GAN adversarial training with multiple specialized discriminators. SMUGGLER achieves high-quality text generation with orders of magnitude fewer parameters than traditional approaches while demonstrating resistance to catastrophic forgetting. Experimental results on Shakespeare text generation show that our approach enables efficient, high-quality generation on consumer hardware without requiri…  ( 13 min )

Hey everyone, I recently developed an open-source tool called Email RAG Assistant to help manage and make sense of my overflowing inbox. It's a local app that: 📩 Summarizes emails into concise one-liners 🗂️ Automatically categorizes emails (Urgent, Important, Promotion, etc.) 🔍 Allows natural language queries like: "Did we ever discuss project XYZ?" "How many emails did I receive from xyz@gmail.com last March?" "Summarize my last 50 emails." All processing is done locally to prioritize privacy. I'm using NVIDIA NIMs for inference, but I'm exploring integrations with local LLMs to enhance privacy further. The project is still in its early stages, and I'm looking for feedback, suggestions, or contributions. Here's the GitHub repository: https://github.com/namanmistry/EmailRAG Would love to hear your thoughts or any ideas for improvement!  ( 3 min )

If by the end of 2025, you still actively hire people whose 40-hour work mostly consists of writing and visualizing SQL queries, you might be losing a lot of money. If you are making data-driven decisions on multiple fronts, from product to sales, marketing, and business in general, then in 2025 it's time for you to reconsider how exactly your Data Analysts spend their time. The problem you might try to solve by hiring more Data Analysts is that they have too much work to do on a daily basis. If most of their work consists of translating product/sales/marketing requests into SQL queries and those into dashboards, PDFs, or spreadsheets, then hiring more won't help because the problem is not in a bigger workload but rather in how your Data Analytics team handles that workload.

Muito já se discutiu sobre as funcionalidades da IA Generativa: modelos de linguagem, engenharia de prompts, automação de conteúdo. Mas o verdadeiro ponto de inflexão não está na tecnologia em si — e sim na sua capacidade de subverter modelos de operação que antes pareciam inquestionáveis. Não se trata mais de "adotar IA" como ferramenta, mas de compreender a IA como um agente de transformação organizacional. Alguns sinais são evidentes: Propostas comerciais que levavam horas para serem montadas agora podem ser redigidas em minutos, com base em dados contextuais e históricos de negociação. Campanhas de marketing não precisam mais ser montadas do zero: são concebidas, testadas e ajustadas por sistemas autônomos com base em comportamento e intenção. A IA Generativa não está apenas automatizando processos. E, talvez mais importante: está alterando o que esperamos das organizações e dos profissionais que nelas atuam. O risco real não é ser substituído pela IA. Não é mais suficiente usar IA. A pergunta, então, não é mais “como aplicar essa tecnologia?”. Sua organização está preparada para repensar seus fundamentos operacionais à luz da Inteligência Artificial Generativa — ou será refém de sua própria inércia? 📌 O debate precisa sair do nível técnico e alcançar o nível estratégico. A IA Generativa não é uma revolução do como. É uma disrupção do por que e para quem as coisas são feitas.  ( 3 min )

In a world where digital transformation is no longer optional, choosing the right cloud provider is one of the most strategic decisions a business can make. But here’s the kicker — most businesses compare providers solely based on cost or brand name. And that’s where they go wrong. AWS has the widest range of services, but are you using them efficiently? Azure integrates deeply with Microsoft products, but is that always an advantage? Google Cloud boasts AI and data capabilities, but what if your use case doesn’t need it? If you’ve ever asked: “Which cloud is the best?” “What’s the real difference between AWS, Azure, and GCP?” “Which provider is right for my workload?” … you’re not alone. We’ve seen startups and even large enterprises spend weeks debating, only to realize they missed core decision criteria. Here’s what often gets overlooked: Compliance & Governance: Which cloud helps you stay audit-ready with less manual overhead? Hidden Cost Models: Are you aware of ingress/egress charges and region-based billing quirks? Developer Experience: How fast can your team get up and running with a new toolset? Multi-Cloud or Vendor Lock-in? Should you optimize for performance, flexibility, or both? These questions aren’t just technical. They’re deeply tied to your business strategy and long-term scalability.

Alright folks, let's talk persistence. If you've been following along with the Vercel AI SDK v5 canary journey, you know we've covered a lot about the new message structures (UIMessage, UIMessagePart), how the client-side state is managed with useChat (especially with that id prop behaving like a mini ChatStore), and how the server-side flow including onFinish and tool calls works. Now, how do we actually save all this rich conversational data so users can come back to their chats? This isn't just about stashing some text in a database anymore. With V5, we're dealing with structured, multi-part messages that are key to those "generative UI" experiences. Getting persistence right means your users get a pixel-perfect restore of their chat, tools and all, and you, the developer, get a system …  ( 37 min )

Alright folks, settle in. We've been exploring the Vercel AI SDK v5 canary in this series, and today we're tackling a big one: Tools. If you're building any kind of agentic behavior, or just need your AI to interact with the outside world (or your own app's functions), this is where the rubber meets the road. v5 brings some serious structure and developer experience improvements to how tools are defined, called, and represented in the UI. As a quick reminder, we're building on concepts from previous posts: UIMessage and UIMessagePart (the new message anatomy), v5's streaming capabilities, V2 Model Interfaces (especially LanguageModelV2FunctionTool), and the overall client/server architecture.

When working with SQL, one of the common inquiries developers face is whether the CASE statement in their SELECT clause effectively filters records or if they also need to replicate the same conditions in the WHERE clause. This question is particularly pertinent when grouping certain entries, such as teams, and seeking clarity on how SQL evaluates these expressions. Understanding SQL CASE and WHERE Clauses The CASE statement is primarily used to create conditional logic inside your SQL queries, particularly in the SELECT clause. Its purpose is to return specific values based on the conditions you define. However, the WHERE clause serves a different function; it limits the rows returned by the query based on certain conditions. Why You Might Need Both CASE and WHERE In your specific example…  ( 4 min )

What is @Scope This is a class-level annotation that allows the developer to define the scope of a Spring bean. By default, all Spring beans are singletons, but by using this annotation, you can modify that to the following scopes: singleton: the default one, where Spring will create a single instance and share it throughout the application wherever the bean is needed. Prototype: This scope creates a new instance whenever the bean is requested. Request: Spring will create an instance of the bean that will live until the HTTP request is done. session: Spring will create a bean specific for that session; for each session, it will be a new bean. Resource management: This annotation will give you the flexibility you need to manage the resources of your application and help you have more cont…  ( 7 min )

Introduction Docker registries are essential nowadays in a world of containerized workloads. Want to run your app on Kubernetes? You need to push it to a registry first. If you don't want to pay for a managed, private registry service, you self-host your own. The biggest pain point of Docker registries is storage. If you choose to store registry data on a local disk, you are limited by capacity. Over time, registries accumulate a lot of garbage in the form of blobs referenced by old images that are not needed anymore. Many registry implementations, such as CNCF Distribution, offer garbage-collection mechanisms to delete unreferenced blobs and free up storage space. However, for that to happen, old images (tags) referencing them have to be deleted first. There are implementations like Har…  ( 4 min )

Read this article on Signadot. Testing in-progress changes together, across services, without merging early or coordinating a full rollout, shouldn’t be so painful. “Hey, don’t merge that yet, I still need to test with my service.” Sound familiar? Coordinating changes across microservices during feature development always starts simple. When your whole stack fits in a single repo or an EC2 box, it’s not a big deal. But fast-forward a bit, and you’re juggling 20, 40, maybe hundreds of services owned by different teams, moving on different timelines, and depending on each other in subtle, undocumented ways. Suddenly, a small change to an internal API breaks someone else’s staging. A frontend pull request (PR) is stuck waiting on a backend deploy.

When I started learning FE, I began with React - like many others. It's the most popular library, and if you search for job opportunities there are abundant. And at that stage, you should have only one goal/priority, getting hired and gaining experience. So it's only reasonable to start with React. I learned React through class component, and yes, they are deprecated. But understanding gave me deeper grasp of how React works under the hood (lifecycle methods, binding, rendering). Eventually, I landed my first job working on Vue project. It wasn't a conscious shift, but it was a opportunity. Over time I came to appreciate Vue, and while writing this, I feel like a need to promote it. Especially through lens of someone who also mentored new developers in React, on bootcamp.

E talvez você se identifique... Desde 2023 venho trabalhando como dev profissionalmente. Sempre fui o tipo de dev "raiz", que gostava de codar, passar horas (ou noites inteiras) imerso em projetos que nem eram meus. Saí de outro estado pra Natal-RN com a cara e a coragem. Aluguei um canto só com a roupa do corpo e fui construindo meu espaço — e finalmente, trabalhando como dev. Amava o que fazia. Mas com o tempo, o cenário mudou. A inflação subindo, custo de vida aumentando, e meu salário... estagnado. A vontade de procurar empregos melhores chegou, deu certo, o salário subiu... etc. Mas há alguns meses, no fim de 2024, percebi que tinha perdido o amor pela programação. O código virou só uma moeda de troca. Eu só queria o dinheiro. E aí veio o maior problema: ❌ Não me atualizei ❌ Fiquei pra trás ❌ Acabei o último contrato PJ e tive uma dificuldade ENORME pra me realocar Enquanto devs realmente bons escolhem onde querem trabalhar, eu tava no limbo, tendo que dar vários passos pra trás. A pergunta martelava: “O que tem de errado comigo?” Depois de muito pensar (e muita autoanálise), percebi: Eu tinha perdido meu lado dev raiz. Aquele que curte aprender, codar por prazer, mergulhar nos porquês das coisas. Tava tudo no automático. Então, comecei do zero de novo. Voltei pro básico: codando, lendo, contribuindo, errando, aprendendo. Dessa vez com prazer. E percebi que tinha me desviado do meu caminho. Antes de olhar pra vaga, eu perguntava: “Quanto paga?” Se não fosse "bom o bastante", eu nem tentava. Agora, a primeira pergunta é outra: “O que posso aprender aqui?” Voltei a contribuir, voltei a movimentar meu GitHub, voltei a fazer parte da bolha dev disso que eu gosto, que eu sempre sonhei, e de onde eu simplesmente me perdi. E aí? Você ainda é dev, DEV? Ou tá só no piloto automático?  ( 3 min )

Why I Built Sona Modern programming languages weren’t built with neurodivergent or first-time coders in mind. That’s a gap I couldn’t ignore. As a self-taught developer, I spent years battling syntax errors, inconsistent tooling, and steep learning curves — not because I lacked motivation, but because the language design just wasn't made for brains like mine.

When set to imagine practical, easy-to-use, lightweight applications of Divooka, a visual novel game framework is one of those that came to mind. Visual novels should be such a straightforward type of application to build, yet surprisingly, it's not generally easy to find ready-to-use tools available for them. Of course, one can use Defold, Godot, Unity 3D, or even Unreal to build such a game — or the more technically inclined might just use SFML or other lower-level graphics libraries. Still, it's a lot of work to get a conceptually straightforward task done. Much like building an LLM agent or chaining different AI services together — it's straightforward, it's visual, it describes some kind of workflow or dataflow — then it's a good fit for Divooka. Visual novels fundamentally consist of…  ( 4 min )

If you're transitioning from JavaScript to TypeScript, you may encounter type-related issues that can be frustrating. In this article, we'll delve into how to properly push an object into a MongoDB array using TypeScript and address common errors you may face in the process. Understanding the Error Your current error occurs because TypeScript is more strict with types compared to JavaScript. The error message you’re experiencing: Type '{ answers: {}; }' is not assignable to type 'PushOperator'. This suggests that TypeScript expects a specific type for the answers field, but you are passing an empty object {}, which doesn't match the expected type. Setting Up Type Definitions To resolve this, you need to define the type of the answers array properly. Assuming that answerObj represents the …  ( 4 min )

A Compiled Programming Language is one where the source code is translated into manchineel code (executable code) by a compiler before the program can run. [Source Code] → (Compiler) → [Machine Code] → [Executable File] [Executable File] → (CPU executes) → Program runs _Source Code _ :- A programmer writes a code, which is called human readable language. Compiler :- A special program, the compiler, takes the source code as input. Analogy Machine Code :- Compiler translates the source code into manchineel code, which is a set of instruction the CPU can understand. Executable file A structured file format (like .exe, .out, .elf etc) that contains: Machine Code Metadata (like symbol tables, headers, memory layout) This is the final output produced by the compiler.

We are living in an exciting era for software development. It has always been an industry of constant evolution, but the rise of artificial intelligence has multiplied the productivity of those who adopted it early. This new reality, with teams capable of building faster than ever, shines a light on something many leaders still don't want to see: the main bottlenecks are often not in development, but in how we manage processes and make decisions. When developers become more efficient, tasks are delivered faster, and AI tools can automate or accelerate repetitive work, the real obstacles are exposed: unnecessary processes, unproductive meetings, outdated hierarchies, and a constant need to “feel in control.” All of this slows teams down. At the root of the problem is often a human flaw: dis…  ( 5 min )

Solana has made a name for itself in the blockchain space as one of the fastest and most scalable platforms in the industry. But what’s the secret behind its speed? It all starts with time. More specifically — Proof of History (PoH). In this blog post, we’ll break down what PoH is, how it works, and how it helps Solana achieve high throughput, low latency, and fast finality — all in a way both beginners and developers can understand. In most blockchains (like Bitcoin or Ethereum), time is a vague concept. Each block is timestamped by validators or miners — but there’s no standardized clock. This creates a challenge when trying to organize transactions quickly and securely. Nodes must constantly communicate to agree on order, which slows everything down. 🧠 Enter Proof of History: Time Befo…  ( 4 min )

They promised speed, simplicity, and a better DX. What we got was a set of beautiful lies, niche fantasies, and philosophical dead ends. Modern frontend frameworks love to sell a dream. Let’s talk about the three self-proclaimed rebels of modern frontend: Astro — The Gatsby Ghost in Island Clothing Qwik — The Resumable Kernel That Forgot the Humans Solid — The Signal Soloist in React's Orchestra Together, they form the Zukkoke Three — each chasing a different ideal, but none equipped to win the war. Astro sells the fantasy of zero-JS by default. Clean HTML. Minimal payloads. Islands of interactivity. Astro is just Gatsby rebranded. It inherits the same flaw: It works great until your app grows. Then you’re back to hydrating islands, shipping frameworks, and juggling scripts. Astro’s true n…  ( 6 min )

Hello, hello! So last week we learned about using your own inbox to capture all your to-dos into a single place? Well, if you followed my advice and did "The Great Inbox Dump," you're probably staring at a mountain of tasks and wondering, "Now what?" Don't worry, my friend. This week, we're diving into the next step of processing everything in that inbox! The goal for this part is to get your inbox to 0, meaning there is nothing left in it you need to process. This will actually be your goal every day (ish) moving forward...but more on that later. Before we dive in, you're going to need a couple of things: A trash bin.

You get a message from the Customer Success team, "can someone please help me identified what is wrong with this?", you find yourself with some time on your hands and decide to help out. "Yes, I can help you out with this. Do you know what are the steps to replicate this issue?". If you are lucky Customer Success says yes and gives you the steps to replicate, on the other hand they will say no. If they said no that means they probably spent a good amount of time trying to replicate the issue but were not able to, now it is on you to guess what what the problem is. Good luck.

Introduction Experiencing a segmentation fault in your Perl script can be quite frustrating, especially when everything seems to execute correctly. If you're encountering a segmentation fault immediately after calling exit 0;, yet your script completes its logic successfully, it indicates an underlying issue that needs to be addressed. This article aims to help you diagnose and resolve segmentation faults in your Perl scripts, focusing on factors such as global destruction and diagnosing techniques. Why Does This Happen? Segmentation faults usually occur due to memory management issues, such as dereferencing invalid pointers or memory corruption, which aligns with the error message you received: mremap_chunk(): invalid pointer. In the case of Perl, this can happen if your script has global…  ( 5 min )

My AI-Driven Coding Workflow: Fast, Dirty, Smart For years, I’ve followed a simple, effective development rhythm: Refactor the existing code to make space for what’s coming. Spam code the new part—quick and dirty—just get it working. Refactor again, clean it up, make it readable and reusable. Commit. It’s always worked. It still does. But now there’s AI. The last few years have made AI coding assistants usable, stable, and practical. So I’ve adapted my process. Here's how it looks today: Start with a clean working tree. No changes, no mess. This has always been good practice, but it’s critical now. Why? Because AI can (and will) generate garbage. If it does, you need to scrap everything fast. You can’t "undo" AI-generated logic. You just reset. Whether by hand or with AI help, p…  ( 4 min )

The result is a dynamic, interactive assistant that not only answers questions but also performs actions, making HR support more efficient and engaging f…  ( 4 min )

A good programming language should model it's domain in the most straight-forward way - that way there are no rough edges, no friction. The programmer has no gotchas to work around, the code flows naturally. Distributed programming in modern mainstream languages is not that experience, and in this blog we will go over a part of the solution, the one having to do with coordination of distributed actors. OOP models a program as an interaction between objects, and its implementation in most modern languages work well in a single-threaded context. But as soon as concurrency gets introduced - you either introduce a whole different mechanism than the objects you've been building with up til this point (threads and mutexes and thread-local variables), or an event loop, and a split in the laguage …  ( 7 min )

When you need to deploy a simple HTML page (like one generated by AI), or quickly share some design drafts, or deploy a small website from a ZIP package, what tools do you usually use? A lot of the time, you either find hosting too expensive or the setup process too complicated. Recently, I discovered an online tool called Pages Drop, and it seems pretty neat. It's essentially a place for hosting and sharing files, and crucially, it's completely free and very convenient to use. Why do I think it's worth sharing? Mainly for these reasons: Although there are similar products, such as Tiinyhost, Static App, etc., the free plans have very few resources and are very restrictive. The free tier is quite generous: Completely Free: The core features are genuinely free to use. Unlimited File Upl…  ( 4 min )

Hello Dev.to readers! This time, we decided to adopt a slightly more serious tone and tackle a serious topic. In our New Gen Atari project, we hit rate limits hard. After that mess, we finally turned to the documentation. To keep you from falling into the same trap, I wanted to write a piece with above-average seriousness. API rate limits cap the number of requests you can make to an API in a given timeframe (e.g., 100 requests per minute). Exceeding these limits results in rejected requests, disrupting your application. They’re standard across platforms, whether free or paid tiers. Limits serve three key purposes: Security: Protect servers from malicious request floods. Resource Management: Ensure fair access for all users.

I recently set up Home Assistant and started exploring the world of smart home automation. One of my first—and now favorite—automations is part of my morning routine. Let’s be honest: waking up early sucks. Alarm clocks are loud, annoying, and stressful. I wanted something more peaceful to get me out of bed. And I found it… I wake up through the smell of coffee and the gentle bubbling sound of a moka pot. 😌 I bought this moka machine from Bialetti: https://www.bialetti.com/ee_en/moka-elettrika.html It’s called the Moka Elettrika, and it runs on electricity. I connected it to a smart plug that’s controlled by Home Assistant. At 7:55 AM, the smart plug turns on, powering the moka pot. The moka starts brewing right away. At 8:10 AM, the plug turns off again. By the time I'm awake, the apartment smells like fresh coffee, and I hear that cozy, comforting moka pot bubbling away. It’s such a calm and natural way to wake up—no loud noises, no stress. This tiny automation has made a huge difference in how I start my day. If you're into smart home stuff (or just love coffee), give it a try!  ( 3 min )

This post was originally published on Medium. I'm resharing it here for fellow developers and tech learners focused on productivity and AI tools. In 2025, AI is no longer just a buzzword. It’s a reliable assistant, a writing partner, a research analyst, and even a decision-making guide. If you're a solo developer or working in a small team, AI tools can easily fill the role of a full-time assistant — helping with writing, planning, organizing, and automating your workflow. Here are 5 AI tools that can genuinely replace or outperform a human assistant: ChatGPT (OpenAI) Research, summarization, planning, brainstorming GPT-4 Turbo supports long context conversations Great for developers to generate test cases, ideas, and plan features Notion AI Meeting note summarization, task extraction, and content generation Blends into your project workflows perfectly Dev teams can use it to log retrospectives, docs, and updates GrammarlyGO Tone refinement, rewrites, and quick replies Useful when writing client emails, proposals, or documentation Magical Automates repetitive typing and form-filling You can set text snippets for common code comments, support replies, etc. Claude AI (Anthropic) Reliable for long-form Q&A, documentation, and secure data handling Great for knowledge-heavy tasks and documentation generation If you're spending time on repetitive tasks — planning, writing, summarizing — these tools can handle them for you. They don’t just save time — they multiply your output. Try one this week and see the difference. ✍️ Written by @denizgokbudak 📚 Frontend developer exploring React, Next.js, and AI tools.  ( 3 min )

There’s a strange paradox in tech: someone can be a solid developer, lead projects, write clean code, and still fail interview after interview. Not once, but over and over again. And we’re not talking about juniors. I’ve seen senior engineers freeze mid-sentence, forget terminology, or just walk away feeling like they bombed, even though they knew the answers. If that sounds familiar, you’re not alone. I’ve worked with developers for years: hiring them, preparing them, evaluating them. And here’s the truth: if you’re struggling with interviews, it doesn’t mean you're unqualified. It means the format is broken. In theory, a technical interview checks if you know your stuff. In reality, it’s a pressure cooker. Here’s what it throws at you: limited time unfamiliar phrasing of questions z…  ( 4 min )

Given a string s, find the length of the longest substring without duplicate characters. Example 1: Input: s = "abcabcbb" Input: s = "bbbbb" Input: s = "pwwkew" Constraints: 0 int: char_set = set() left = 0 max_length = 0 for right in range(len(s)): while s[right] in char_set: char_set.remove(s[left]) left += 1 char_set.add(s[right]) max_length = max(max_length, right - left + 1) return max_length Each character is added and removed at most once → O(n) Set gives constant time lookup → fast Use this sliding window + set pattern whenever: You need the longest substring/subarray with no repeats You need to maintain a dynamic window of valid elements Time & Space Complexity: Type Value Time O(n) (each character is visited at most twice) Space O(min(n, m)) where m is the character set size (e.g. 26 lowercase)  ( 3 min )

Are you building a file upload feature for your web app? Step 1: Generate a Signed Upload URL on the Server Click here to read article about generating signed url. Here’s an example response from your backend API: { "signedUrl": "https://your-bucket.r2.cloudflarestorage.com/filename.png?X-Amz-Algorithm=AWS4-HMAC-SHA256&..." } Step 2: Upload from the Frontend Using Fetch ✅ HTML: Upload ✅ JavaScript: async function uploadFile() { const input = document.getElementById('fileInput'); const file = input.files[0]; if (!file) return alert("Please select a file!"); // 1. Get a signed upload URL from your backend const res = await fetch(`/api/r2-signed-url?filename=${encodeURIComponent(file.name)}`); const { signedUrl } = await res.json(); // 2. Upload the file directly to R2 const uploadRes = await fetch(signedUrl, { method: 'PUT', body: file, }); if (uploadRes.ok) { alert("✅ Upload successful!"); } else { alert("❌ Upload failed."); } } Why This Works No extra libraries (no axios) Faster uploads because the file goes straight from browser → Cloudflare Secure: your app’s R2 credentials stay on the server Scalable: you don’t stress your backend with file payloads Don't Forget CORS!

Hey everyone! 👋 I’m excited to share something we’ve been working on for a while: Prompt Inspector 🕵️‍♂️ – a browser-like inspect tool for debugging and understanding your prompts for large language models (LLMs). 🧑‍💻 A few months ago, we were deep into a project that analyzed GitHub repos using LLMs. Our prompts were getting longer and more complex, and we kept running into the same problem: 🤔 Which part of my prompt was actually influencing the output? It felt like we were flying blind, tweaking random lines and hoping for the best. It reminded me of the early days of web development-before browser devtools made debugging HTML and CSS so much easier. 🕸️ That’s when it hit us: 💡 Why isn’t there an “Inspect Element” for prompts? Prompt Inspector is our answer to that question. …  ( 4 min )

Introduction In Rust, handling files and processing their content efficiently is crucial, especially when dealing with potentially large files. A common scenario involves reading lines from a file and splitting those lines into individual tokens based on whitespace. However, you might encounter a compilation error due to how Rust handles lifetimes and references. In this article, we will explore the origin of this issue and provide a solution that returns an iterator of owned String values without allocating too much memory upfront. Understanding the Compilation Error When you attempt to return a value that references function parameters, Rust will flag this as an error. Your original code attempts to utilize the .split_whitespace() method, which returns slices of the original string. The …  ( 4 min )

Google just paid $1.375 billion to Texas for secretly tracking users, collecting geolocation, voiceprints, and facial recognition data even with privacy settings disabled. The headlines scream “Big Tech scandal” — but here’s the real message: If your app handles user data, you’re part of this conversation. And if you’re using tools like Firebase, Google Analytics, or Meta Pixel in production without understanding what’s being captured, you’re one misconfigured SDK away from a privacy disaster. 🔍 So, What Should Developers Do? Re-check what your analytics are logging. Google Analytics 4 tracks more than you think by default, especially if you’ve enabled Enhanced Measurement. Alternative: Try Plausible or PostHog. They’re privacy-first, self-hostable, and GDPR-compliant. Audit your use of location data. If you’re using React Native Geolocation, are you requesting location only when needed? In web apps, check the navigator. Geolocation calls, are you storing or sharing that info? Facial recognition libraries? Tread carefully. Read your dependencies’ privacy policies. Cookies and localStorage: keep them clean. Use libraries like cookie-consent and tools like Cookiemonster.dev to flag risky behavior early. 🧠 The Bottom Line As devs, we build the foundation of user experiences, and that includes privacy-first defaults. Not because it’s trendy, but because it’s now a requirement.  ( 3 min )

When we talk about giving feedback, most of the advice out there focuses on how to say the thing. But what I have learned over time is that the real magic happens before the conversation even starts. Setting the stage can be the difference between feedback landing as a gift or feeling like an attack. Some of the most effective feedback conversations I have had - both from giving and receiving - actually started with a letter. When there's a lot to say, taking the time to write it down helps in more ways than one. It lets you rewrite, refine, and make sure the message you intend is the message that gets carried forward. You can catch moments where your tone might be too harsh, or where you're speaking from frustration instead of clarity. From the recipient's perspective, it's a game-change…  ( 4 min )

Welcome to the next pikoTutorial ! Imagine you're building an application that processes some data and once it's done, the user needs to be notified about the result. Since you don’t want to hard-code the notification logic, it’s better to allow the user to register a custom function that will be called automatically after the data processing completes. std::function for callback registration One of the most flexible ways to implement callbacks in C++ is by using std::function. std::function can store and invoke any callable object (functions, lambdas, or function objects) that matches a specific signature. The overall syntax is: std::function name; Let’s define a ProcessData unction that accepts a callback and notifies the user once processing is complete. #include #include // Type alias for the callback type using CallbackType = std::function; // Function accepting callback as an argument void ProcessData(const CallbackType& callback) { // Simulate data processing std::cout << "Processing data" << std::endl; // Notify user via callback callback(true); } // Callback function definition void Callback(const bool result) { std::cout << "Callback called! Result: " << result << std::endl; } int main() { // Register a callback using an existing function ProcessData(Callback); // Register a callback using lambda function ProcessData([](const bool result) { std::cout << "Lambda called! Result: " << result << std::endl; }); // Register using callable object CallbackType cb = [](const bool result){ std::cout << "Callable called! Result: " << result << std::endl; }; ProcessData(cb); }  ( 3 min )

In the world of keyboards, the WASD keycaps hold a special place. These four simple letters—W, A, S, and D—are often seen as the backbone of gaming.

In this post, I’ll show you 7 underrated tricks that can simplify your code, enhance readability, and make you look like a JavaScript pro in 2025. ?. const username = user?.profile?.name || 'Anonymous'; ✅ Avoids errors when deeply nested properties are undefined. Cleaner and safer than long logical chains. ?? const count = inputValue ?? 0; ✅ Returns default only if the left-hand value is null or undefined (unlike ||, which includes 0 or ''). const { title: blogTitle } = post; ✅ Grab and rename properties in one line. const isAvailable = !!value; ✅ Quickly turn any truthy/falsy value into a clean true or false. const user = { name, age }; // same as { name: name, age: age } ✅ Reduces repetition when property and variable names match. const key = 'theme'; const settings = { [key]: 'dark' }; ✅ Build flexible objects based on runtime values. const status = `You are ${loggedIn ? 'logged in' : 'logged out'}.`; ✅ Great for short conditional strings and UI feedback. These tricks may be small, but they add up to cleaner, more elegant JavaScript code. Whether you're working on a side project, fixing bugs, or building production apps—mastering these patterns will level up your skills. ✅ Try using at least 2 of these in your next app! 💬 Got a trick of your own?

Short answer: yes Over the past 5 years, I've learned a lot about communities. I've made many mistakes: I could probably create a 'Community Mistakes 101' crash course! Unfortunately, they didn't teach that in high school, which would have been useful. I learned that a community absolutely must have a specific goal. I also learned that while having an open community is good at the beginning, it becomes nearly impossible to handle and moderate long-term unless you dedicate an insane amount of time to it (trust me, I tried) or you are a bored millionaire lying on the couch all day (which is not my case). Regarding promotion, I've made the mistake in the past of overpromoting communities I created, simply because I was overjoyed about the new adventure. I now think this approach is wrong. it's better if people discover the community on their own. But now I really feel I am ready to do it right. So, why am I writing this? The reason is simple: I've just a new community, and I've decided to use Twitter (sorry, X) for it. The goal is to introduce curious developers to the Rust programming language and help them understand as much as possible. Joining this community is free, just request to join.

When trying to SSH into a newly created Linux server, you might run into a common error like this: $ ssh user@your-server-ip The authenticity of host 'your-server-ip' can't be established. ED25519 key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. Any other names do not know this key. Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'your-server-ip' (ED25519) to the list of known hosts. user@your-server-ip: Permission denied (publickey). This error simply means: “SSH couldn’t find a valid key to authenticate you.” ✅ What Actually Worked ssh ubuntu@your-server-ip You used the correct approach by providing the private key file: ssh -i /path/to/your-key.pem ubuntu@your-server-ip And this worked — because the server was expecting authentication via a specific private key (.pem file), not a default key from ~/.ssh/id_rsa. 🔍 Why This Happens key-based authentication only for better security. When you create a VM or instance, you’re often required to either: Upload your public key, or Download a .pem file that matches the server's authorized key If you try to SSH without specifying the .pem file, the SSH client defaults to using standard key files like ~/.ssh/id_rsa, which likely don’t match what the server expects. 🛠️ How to Avoid This in the Future Always specify the key manually with -i OR Add the key to your SSH agent so it's picked up automatically: ssh-add /path/to/your-key.pem 🧠 Pro Tip chmod 600 your-key.pem This keeps your key file secure and prevents SSH from refusing to use it.  ( 3 min )

When working with C++ and interfacing with API functions, developers often encounter the challenge of passing large blocks of data. In your case, you're constructing a large string using std::ostringstream and need to send this data to an API function, API_function, defined as int API_function(const char* data, int len). The issue arises when the data contains null bytes (0x00), resulting in data truncation. Let’s address how to pass this std::ostringstream payload effectively to the API function without copying it, especially in the context of constrained environments like microcontrollers.

Hi everyone, The game is called BrainsIAAndPixels: it's going to be a 3D title with a pixel art style (even though it's set in a 3D environment), where NPCs won't be rigidly "scripted" but will instead be controlled by real artificial intelligence using pre-trained models running locally. The goal is to create a game where NPCs understand and react to what happens around them, rather than just following a fixed pattern. I'm using Python in Godot, and the AI part relies on ONNX models. Right now, I'm setting up the development environment, testing the AI integration, and building the foundations. The plot and genre aren't fully defined yet (I'm torn between survival, something narrative-driven, or similar), so any ideas are more than welcome. Thanks!  ( 3 min )

Today's note is about something that I, as a new Mac user, had to deal with while setting up my work environment. TL;DR: To run NVDA and JAWS on a Mac, you need to install Windows 11 for ARM in a virtual machine like UTM, and map a spare key to the Insert key with SharpKeys. According to the WebAIM Screen Reader User Survey #10, Windows-only screen readers NVDA and JAWS are used by the majority of users. Just like browsers, screen readers have differences in how they present information, so it's always a good idea to test your website or app using different browser/screen reader combinations. In addition, some of the styling, like box shadows, background images, and so on, is removed when Windows High Contrast Mode (WHCM) is enabled. Sadly, there is no alternative to the WHCM on the Mac.

When working with object-oriented programming in Java, it's common to encounter situations where you want to pass a collection of objects from a subclass (child) to a method that expects a collection of objects from a superclass (parent). This might seem straightforward, but the compilation error you're facing highlights a key aspect of Java's type system, particularly with generics. Understanding Java Generics Generics in Java provide a way to specify a type parameter when defining classes and methods. When you declare a method that takes a list of a specific type, such as List, it expects a list that strictly contains Parent objects, not Child objects. Even though Child is a subclass of Parent, List is not considered a subtype of List. This is due to Java's type sa…  ( 5 min )

In Laravel projects or any large scale PHP application it's common to create helper files that contain reusable functions. These helpers make your code cleaner and more efficient. But there's a common issue, defining the same function more than once will cause a Fatal error.. What's the problem? If the same function is declared twice, PHP will throw an error like this: Fatal error: Cannot redeclare function_name() This often happens because of: Repeated includes: Package conflicts: The safe solution To prevent this issue, wrap your helper functions like this: if (!function_exists('sayHello')) { function sayHello() { return 'Hello!'; } } This way, if the function already exists, PHP will skip redefining it, and your app will keep running smoothly. In Laravel projects Even with Laravel’s powerful autoloading and service container, this pattern is essential. It keeps your project safe from unexpected conflicts and ensures maximum compatibility especially when working with custom helpers or external packages.

Recently, on LinkedIn, I've been seeing the posting from Duolingo's team about how they have decided to do away with the whole UX wireframing process. While that might sound rather controversial to most folks, as an experienced professional, I actually do kinda understand where they might be coming from. You must understand that I've been drawing UX wireframes since early 2006. That's almost two decades now. I've done so many wireframes that by now, a lot of what I can do on paper using sketches or even the digital form, I can mentally visualize them inside my head, and I can convert most of them smoothly into UI prototypes. But that is only because of a few factors: I've been doing this a long time. I've become very good at anticipating what a potential user would want. I can easily visua…  ( 6 min )

A year ago, I was just another aspiring entrepreneur with a rough prototype and a dream. Today, I’m running a funded startup, growing a team, and solving a real-world problem I care deeply about. The turning point? A weekend hackathon that changed everything. The Backstory: From Idea to Execution I had a basic MVP, a few sketches, and a lot of late nights fueled by coffee and code. But it wasn’t until I stumbled across a local hackathon that everything started to shift. Enter the Hackathon Over 48 hours, my small team (a designer friend and a college buddy who could code like lightning) pulled off a miracle. We turned my rough MVP into a functional demo, ironed out a compelling pitch, and presented it to a panel of judges — including venture capitalists, product managers, and seasoned foun…  ( 4 min )

When working with the Hanami framework in Ruby, validating parameters is an essential task to ensure the integrity of the data your applications handle. If you've encountered the error 'no anonymous block parameter' while validating your parameters, you're not alone. This common issue arises due to the way blocks are defined and used in Ruby. Understanding the 'No Anonymous Block Parameter' Error In Ruby, when you define a method that takes a block, you generally have to capture that block using a block parameter. The error 'no anonymous block parameter' suggests that the block you're trying to define doesn't have an associated variable to hold the block context. Without this, Ruby cannot process the block correctly, leading to the error. Common Scenario of the Error Let's take a look at t…  ( 4 min )

Defense lawyers have asked a judge to sentence the person responsible for helping post a fake message announcing regulatory approval of Bitcoin exchange-traded funds to roughly a year in prison, countering prosecutors’ request for a two-year sentence. In a May 13 filing in the US District Court for the District of Columbia, Eric Council Jr.’s legal team asked that he be sentenced to no more than one year and one day in prison following his guilty plea. Council was part of a group that took control of the US Securities and Exchange Commission’s (SEC’s) X account in 2024 through a SIM swap attack, posting a message that suggested the regulator had approved spot Bitcoin (BTC) exchange-traded fund listings for the first time. “A sentence of twelve months and one day serves the ends of justice…

Opinion by: Jupiter Zheng, Partner Liquid Fund at HashKey Capital Whenever Bitcoin falls in value, the narrative is always the same: It’s failing as a hedge against inflation. In the eyes of critics, Bitcoin is not the “digital gold” that so many others claim it to be. With gold hitting all-time highs, these critics have grown louder. If Bitcoin is an inflation hedge, they ask, why isn’t it also rallying as investors seek safety? Even in today’s bearish, high-inflation environment, the cardinal truth holds: Bitcoin is an inflation hedge — arguably the most important one for long-term capital preservation the world has seen.  Strength in scarcity Bitcoin has a hard cap of 21 million coins, with full circulation expected by 2140. This built-in scarcity mirrors gold, which has historically se…

Institutional demand for Bitcoin is growing, as Coinbase, the world’s third-largest cryptocurrency exchange, recorded its highest daily outflows of Bitcoin in 2025 on May 9. On May 9, Coinbase saw 9,739 Bitcoin (BTC), worth more than $1 billion, withdrawn from the exchange — the highest net outflow recorded in 2025, according to Bitwise head of European research André Dragosch. “Institutional appetite for bitcoin is accelerating,” Dragosch added in a May 13 X post. Source: André Dragosch Related: Nasdaq-listed GDC plans to buy Bitcoin and TRUMP memecoin for $300M The outflow occurred as Bitcoin traded above $103,600 and just days after the White House announced a 90-day reduction in reciprocal tariffs between the US and China, easing market concerns and lifting broader investor sentiment. …

Venture capital firms remain critical to infrastructure development in the Bitcoin ecosystem, despite pushback from some in the community, according to builders speaking at the Token2049 conference in Dubai. Charlie Yechuan Hu, CEO of Bitcoin layer-2 protocol Bitlayer, shared his insights on venture capital (VC) firms in the Bitcoin (BTC) ecosystem. Hu told Cointelegraph that he views many VC firms in the space positively, as they offer support to early ventures that need capital to build infrastructure. “You need developers, you need to open up the whole ecosystem foundation, everything,” Hu said. “You need to pay for the cloud, like AWS or RPCs, all that, servers […] So, we have to have VC on that.“ Hu argued against the usual Bitcoiner ethos that argues against outsider capital, saying,…

Bitcoin defied expectations in April, delivering double-digit gains while posting lower volatility than major traditional assets. According to analysts at Galaxy Digital, Bitcoin’s (BTC) realized volatility over the past 10 trading sessions dropped to 43.86, lower than the S&P 500’s 47.29 and the Nasdaq 100’s 51.26 — an unusual “positioning for a digital asset traditionally known for its outsized volatility.” The data point comes against a backdrop of renewed financial turbulence. Since US President Donald Trump’s Liberation Day tariff announcement on April 2, traditional markets have wobbled. The Nasdaq Composite is flat, the Bloomberg Dollar Index fell nearly 4%, and even gold (typically a safe haven) briefly hit $3,500 per ounce before pulling back to a 5.75% gain, Galaxy Digital analys…

Arizona Governor Katie Hobbs vetoed two key cryptocurrency-related bills that aimed to expand the state’s involvement in digital assets while signing a strict regulatory measure targeting Bitcoin ATMs. On May 12, Hobbs rejected Senate Bill 1373, which sought to establish a Digital Assets Strategic Reserve Fund. The fund would have allowed Arizona to hold crypto assets obtained through seizures or legislative allocations. “Current volatility in cryptocurrency markets does not make a prudent fit for general fund dollars,” she stated in her veto letter. “I have already signed legislation this session which allows the state to utilize cryptocurrency without placing general fund dollars at risk,” she added. That decision followed her veto of Senate Bill 1025 — the more ambitious “Arizona Strate…

Hong Kong-based Animoca Brands is preparing for a listing in New York, citing US President Donald Trump’s relaxed regulatory stance on digital assets as a window of opportunity to enter the world’s biggest capital market. Animoca executive chair Yat Siu told the Financial Times that an announcement may be made soon, with the company currently evaluating various shareholding structures. Siu said the decision to pursue a US listing would not hinge on market conditions but rather on timing and strategic positioning.

The lawyer for a group of Caitlyn Jenner memecoin buyers said they will continue their legal fight against the ex-Olympian after a judge threw out the case for failing to adequately support the securities and fraud claims it brought. Jenner had escaped a class-action lawsuit from buyers of her self-titled memecoin, Caitlyn Jenner (JENNER) after California District Court Judge Stanley Blumenfeld Jr. said in a motion filed on May 9 that it was “sufficient to conclude that all nine causes of action are deficient” and sided with Jenner in dismissing the suit in its entirety for failure to state a claim. He allowed the class group to amend its suit, which must be filed by May 23, but warned it had “to be more focused and judiciously pleaded” than the original. A lawyer for the class group, Fitz…

A British High Court has issued a restraining order against computer scientist Craig Wright, preventing him from filing further defamation suits.  In a May 12 judgment, High Court Judge Edward Mellor said Wright’s repeated false claims and aggressive legal actions created legal “hell” for individuals and developers in the Bitcoin (BTC) community, adding that Wright sought to “weaponise legal systems” to intimidate and silence critics. His lawsuits forced people into costly and time-consuming legal defenses, often based on fabricated evidence, the judge added as he handed out a General Civil Restraint Order or injunction against Wright, prohibiting him from filing any more civil claims or applications in the High Court.  The court highlighted how this strategy was part of a pattern of abusi…

The US government has asked a federal judge to impose a two-year sentence for Eric Council Jr., the individual who helped post a fake message announcing the approval of Bitcoin exchange-traded funds through the Securities and Exchange Commission’s (SEC’s) X account. In a May 12 filing in the US District Court for the District of Columbia, prosecutors recommended Judge Amy Berman Jackson sentence Council to two years in prison for his role in posting a message to the social media platform X suggesting that the SEC had approved spot Bitcoin (BTC) exchange-traded funds (ETFs) for the first time in January 2024. The fake announcement, which shook markets in the roughly 24 hours before the regulator actually approved spot Bitcoin ETFs, led to the arrest of Council. “This case deserves a guideli…

Key takeaways: Bitcoin lags as investors shift toward stocks after the US and China strike a deal that could end the current trade war. Macroeconomic conditions are swinging away from gold investing and back to stocks.  Bitcoin (BTC) reached its highest price in over three months at $105,720 on May 12, but was unable to maintain its bullish momentum.

Opinion by: Robin Singh, CEO of Koinly Is there a catch for Bitcoin hodlers, with the asset’s price up over 600,000% since the beginning of 2013?  Perhaps — if governments keep waking up to Bitcoin’s value, the whole “you only pay tax when you sell” mantra could soon be a thing of the past. What if a wealth tax is the answer for revenue-hungry tax agencies with no time to lose? It’s a yearly tax on a person’s total net worth — cash, investments, property and other assets — minus any debts, applied whether or not those assets are sold or generating income. The idea is to boost public revenue and curb inequality, mainly by taxing the ultra-rich. A wealth tax takes a clip off what you own, not what you earn. Countries such as Belgium, Norway and Switzerland have had wealth taxes baked into th…

We do want trade. We want more balance in trade.” Joint statement on US-…

What is RISC-V? RISC-V, pronounced “risk five,” is a modern open-source instruction set architecture (ISA) based on reduced instruction set computer (RISC) principles.

Social engineering in crypto, explained In the world of cryptocurrency, security goes beyond just protecting your wallet with a password or private key. One of the most deceptive and increasingly dangerous threats to crypto users today is social engineering.

Key takeaways Though Bitcoin doesn’t support native staking, holders can earn yield through centralized lending platforms, Wrapped Bitcoin (WBTC) on Ethereum, and Bitcoin-related networks like Babylon and Stacks. WBTC allows BTC holders to participate in lending, liquidity pools and yield farming on Ethereum-based DeFi platforms like Aave and Curve but introduces bridge and smart contract risks. Protocols like Babylon and Stacks use mechanisms like native time-locked scripts or stacking to offer rewards without removing BTC from the Bitcoin blockchain. Custodial, smart contract and regulatory risks persist. Bitcoin’s community also remains divided on whether Bitcoin yield generation features align with its decentralized and trust-minimized ethos.

Bitcoin’s potential price reaction to a trade deal between the United States and China could give insights into whether Bitcoin is being used as a safe-haven asset in the current market.

On May 9, the Northern Mariana Islands Senate voted 7-1 to override Governor Arnold Palacios' April 11 veto of the bill, which would allow the Tinian local government to issue licenses to internet casinos and includes a provision for the Tinian treasurer to issue, manage and redeem a “Tinian Stable Token.”  The bill will now head to the 20-member Northern Mariana Islands House, which will need a two-thirds majority vote to override the veto and pass the bill into law. If the House is quick to pass the bill, the Tinian government could be in the lead for the first US …

Censorship-resistant “dark stablecoins” could come in increasing demand as governments tighten their oversight of the industry.  Stablecoins have been used for various groups to store assets due to a lack of government interference; however, with regulations pending, that could soon change, Ki Young Ju, CEO of crypto analytics firm CryptoQuant, said in a May 11 X post. “Soon, any stablecoin issued by a country could face strict govt regulation, similar to traditional banks. Transfers might automatically trigger tax collection through smart contracts, and wallets could be frozen or require paperwork based on government rules,” he said. “People who used stablecoins for big international transfers might start looking for censorship-resistant dark stablecoins instead.” On the heels of US Presi…

Hardware wallet provider Ledger has confirmed its Discord server is secure again after an attacker compromised a moderator’s account to post scam links on May 11 to trick users into revealing their seed phrases on a third-party website. “One of our contracted moderators had their account compromised, which allowed a malicious bot to post scam links in one channel,” Ledger team member Quintin Boatwright wrote on the Ledger Discord server.  “The issue was quickly contained: the compromised account was removed, the bot was deleted, the website was reported, and all relevant permissions were reviewed and secured.” Some members in Ledger’s Discord channel claimed the attacker abused moderator privileges to ban and mute them as they tried to report the breach, possibly slowing Ledger’s reaction.…

Let’s be honest: most cloud “strategies” I come across aren’t really strategies — they’re glorified lift-and-shifts. On paper, migrating to the cloud promises flexibility, scalability, and cost savings. But in reality? Many organizations just copy their on-prem setup into AWS, Azure, or GCP — and call it done. As someone who’s spent years helping companies build scalable, secure, and cloud-native infrastructure across multi-cloud environments, I’ve seen this mistake over and over. But one project in particular made this painfully clear. The Lift-and-Shift That Didn’t Shift Anything But what I found was this: configured almost exactly like their legacy setup. 2.They managed access using manually configured Security Groups and Network ACLs — trying to mimic their old firewall rules. 3.Scalin…  ( 4 min )

Solana and Ethereum are two of the most popular blockchains in the world. But if you look under the hood, you’ll notice they speak different “languages.” Ethereum uses Solidity, while Solana uses Rust. So… what’s the difference? And why does it matter? Let’s break it down in plain English. Think of Solidity and Rust like languages people use to build apps — just like websites are built with HTML or JavaScript. Solidity was created specifically for blockchains — especially Ethereum. It’s simple, beginner-friendly, and looks a bit like JavaScript. Rust is more like the serious, high-performance cousin. It’s used to build powerful software like games, browsers, and now — Solana. One of the biggest problems in crypto? Bugs and hacks. Solidity, while easier to use, has been behind many major De…  ( 4 min )

What is a Laravel Observer? Observers in Laravel are used to listen for specific events on Eloquent models, such as creating, updating, and deleting records. The main advantage of using them is the ability to delegate the data handling logic to a dedicated class, keeping controllers and models leaner. Imagine you need to perform an action every time a user is created. Instead of writing that logic directly in the controller or the model, you can use an Observer to ensure that the logic is isolated and easier to test. Creating an Observer in Laravel is very simple. Let's take a look at a basic example of an Observer for a User model: php artisan make:observer UserObserver --model=User Open the App\Providers\EventServiceProvider file and register the observer: public function boot() { …  ( 4 min )

I'm thinking about starting a podcast with @blumen where we interview a bunch of somewhat successful / living-their-livelihoods-off-of-music people we went to music school with, and see where they are today. Basically Celebrity Catch Up: Life After I Did That Thing but without the Celebrity and without The Thing. 😬 Typing it out now makes it seem like a pretty bad idea, but I think it could be good information gathering for anyone considering music school or working in music. Plus, it would be amusing for our little cohort of music school grads and a fun way for us to reconnect with some folks. According to music-colleges.com (lol), SUNY Fredonia's music program ranks at #276 (out of 1451 schools they evaluated, so technically in the 20%!!). I imagine a podcast like this about Julliard grads would be much more successful, but those people probably wouldn't have good advice or relatable stories for real, non-prodigious but competent musicians. So far our initial brainstorm has us landing around: 30-45 min max Asking people about: What they studied How much schooling they ended up getting Their most memorable Fredonia experience What they do now Career highlights Career lows How much money they currently make (from music) What their advice would be for anyone pursuing their current career, or the program they studied in school Thoughts?  ( 3 min )

The Editor as a Storyteller: Crafting Meaning Through Cuts Film editing is far more than a technical exercise in arranging images; it is a profound act of storytelling. The editor shapes narrative, rhythm, emotion, and even truth by deciding what the audience sees—and when they see it. This power to construct meaning through selection and sequencing makes the editor an essential co-author of a film’s emotional and intellectual impact. At its core, editing transforms raw footage into a coherent and resonant experience. Through choices in duration, order, and juxtaposition, editors influence how characters are perceived, how themes develop, and how a story unfolds. The emotional arc of a scene—whether tranquil or intense—often hinges more on the cut than the shot itself. Editing allows a f…  ( 6 min )

Have you ever wondered how JavaScript functions can "remember" things even after they've finished running? That’s the magic of closures, and today we’ll break it down with a simple use case: building a custom counter function. We’ll touch on key concepts like function factories and state persistence to bring this idea home. Closures: For example, in our counter, a variable count is defined inside makeCounter(). The inner function (the actual counter) uses this variable. Thanks to the closure, the count is not lost when makeCounter() finishes, the counter function still remembers it. Function Factory: One Function, Many Counters Think of makeCounter() as a factory. Every time you call it, it gives you a brand new counter, like a fresh instance with its own private count. Each counter is completely independent. State That Sticks(State Persistence) The beauty of closures is state persistence. Since count is part of the closed-over scope, it keeps its value between function calls. That’s what allows the returned function to keep incrementing the same number, step by step. The key takeaway: even though makeCounter() is finished, the returned function still has access to everything defined inside it. That’s the closure in action, enabling encapsulation, memory, and a clean way to manage state without global variables. Closures aren’t just cool, they’re powerful. Once you understand them, you’ll start seeing them everywhere in JavaScript. And best of all, they make patterns like private counters, once complex, totally natural.  ( 3 min )

If you're building a product as a solo dev or part of a small team, you've probably struggled with design. You open Figma. You pick a font. Then a color palette. Then you browse some Dribbble shots. Then you go down a dark hole of animations, blur effects, neumorphism... and suddenly you've spent three hours tweaking gradients but your product still doesn't feel right. Here's the problem: you're thinking about design backwards. Design isn't about how your app looks. It's about what it lets people do and how easily they can do it. That's why I follow a dead simple rule: Design functionality first. Make it beautiful later. Design isn't about how something looks it's about what it lets people do. When you focus on visual details too early, you're decorating an idea that hasn't even proven its…  ( 5 min )

Hi DEV community! My name is Jo. I am a Digital Designer and Learning Technologist at the University of Leeds with a specialism in UX design and web accessibility. My coding journey started over lockdown when I completed a coding bootcamp with The Coders Guild, learning HTML, CSS, basic JavaScript, bootstrap, and Git. I will be honest, I don't need to use it every day for my career so I did forget some of what I've learnt since then but I have started to pick it back up again! My background is in graphic design so I hope to utilise my knowledge in this field to create more visually stunning web experiences. Currently with the support of my colleague, I help create bespoke web development projects that supplement the learning within our online course portfolio. For me personally, these projects are very basic (and partly supported by ChatGPT) because I am still learning... but I hope to change that! My goal is get to the point where I am much better and more confident in my skills at front-end web development and require less hand-holding. I also want to create diverse interactive experiences to hopefully foster genuine curiosity for the subject matter with our students and engage them with the learning material. Managers are more interested in boosting the reputation of the university, but the most important thing for me is to promote academia and make learning fun! Most of my posts will be misc stuff I've learnt and will probably be written with bad or inefficient code rather than being effective tutorials so please read with caution! Thank you for coming on this coding journey with me! If you'd like to connect, my LinkedIn profile is linked before (I no longer use any other social media platform anymore for my professional presence). I am in the process of coding my own website so be sure to keep a look out for this in due time! LinkedIn: https://www.linkedin.com/in/jolaw233/  ( 3 min )

“SQL is not about loops—it's about logic.

SQL speaks the language of sets, and when you think in sets, your queries become: Faster More readable Easier to maintain In this article, we’ll compare procedural vs set-based logic with clear examples and best practices. Scenario: Mark all Pending orders as Shipped.

When working with Python and Bash scripts, logging output can become cumbersome, especially when you want to preserve the chronological order of the messages. The challenge you’re facing is that output from your Bash script is appearing in the log file before the output from your Python script due to buffering issues. This article will guide you through the best practices for ensuring that all outputs are recorded in the correct order, using file descriptors effectively. Understanding Output Buffering When Python writes output to a log file, it may use buffering, meaning it collects a certain amount of data before writing to the file. Similarly, Bash scripts can exhibit this behavior as well. When subprocesses are called within Python, outputs can arrive in an unpredictable sequence, there…  ( 5 min )

Back in 2022, my team and I were working on a service which was printing a fairly sizeable amount of logs from a distributed cluster of 20+ hosts: about 2-3 million log messages per hour in total. We were using Graylog, and querying those logs for an hour was taking no more than 1-3 seconds, so it was pretty quick. Infra people hated Graylog though, since it required some annoying maintenance from them, and so at some point the decision was made to switch to Splunk instead. And when Splunk was finally rolled out, I had to find out that it was incredibly, ridiculously slow. Honestly, looking at it, I don't quite understand how they are even selling it. If you've used Splunk, you might know that it has two modes: “Smart” and “Fast”. In “Smart” mode, the same query for an hour of logs was tak…  ( 4 min )

I've just released git-gpt-commit v0.9.0 — a Git extension that uses OpenAI's GPT models to automatically generate commit messages via the git gpt commit command. The default model has been upgraded to OpenAI’s GPT-4o. blazing-fast response speed (about twice as fast as GPT-4.1), allowing it to generate commit messages in an instant. very cost-efficient, at half the price of GPT-4-turbo. Previously, only English was supported. Now, with: git gpt lang You can choose from 12 languages for your commit messages: Previously, there was no option to add prefixes to your commits. Now, with: git gpt prefix You can toggle the inclusion of commit prefixes like feat:, fix:, or refactor:. Previously, you had to write your API key in a .env file in your project directory. Now, with: git gpt open-api-key You can now safely add and manage your OpenAI API key directly from the CLI. .env method is still supported as well. git gpt config You can now view all your current settings at once. Once installed, start by registering your OpenAI API key using the command above. Then, just stage your changes with git add, and run: git gpt commit The tool will analyze the staged changes, send them to the GPT model, and generate a context-aware commit message. You’ll need an OpenAI API key. npm install -g @laststance/git-gpt-commit While IDEs like VSCode and Cursor offer AI-assisted commit message generation, I couldn’t find a CLI tool that does the same — and that’s where I spend most of my time working with Git. Most of the features I personally wanted are now implemented, so I’m pretty happy with this release. Links: GitHub｜npm  ( 4 min )

In this problem, you're given a matrix of integers where each row and each column is sorted in ascending order. The goal is to find the index of the row that contains a specific target value. If the target value is not found in the matrix, return None. This is a common matrix problem that can be solved efficiently by taking advantage of the sorted structure. Instead of checking each cell (which would take O(n × m) time), you can reduce the complexity to O(n + m), where n is the number of rows and m is the number of columns. We make use of the matrix's properties—namely that values increase as we move right and down, and decrease as we move left and up. Start from the top-right corner of the matrix. Use a loop to traverse the matrix: If the current value equals the target, return the current row index. If the current value is greater than the target, move left. If the current value is less than the target, move down. If the loop completes without finding the target, return None. def find_row_with_target(matrix, target): if not matrix or not matrix[0]: return None # Matrix is empty n = len(matrix) # Number of rows m = len(matrix[0]) # Number of columns # Start at the top-right corner row, col = 0, m - 1 while row = 0: if matrix[row][col] == target: return row # Target found elif matrix[row][col] > target: col -= 1 # Move left else: row += 1 # Move down return None # Target not found matrix = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12] ] print(find_row_with_target(matrix, 7)) # Output: 1 print(find_row_with_target(matrix, 13)) # Output: None This solution demonstrates how understanding data structure properties can lead to more efficient algorithms. Instead of brute-force search, a directional approach through the matrix takes full advantage of the sorted nature, resulting in a linear time complexity relative to the dimensions of the matrix.  ( 4 min )

“When sub-second dashboards matter, pre-aggregation is your best friend — and materialized views are the weapon of choice.” In modern SQL-based systems, developers need fast, repeatable reporting queries.

Hey folks 👋 Over the past few months, I’ve been curating a large collection of interesting and useful GitHub repositories — projects that show up on Hacker News, Reddit, Twitter, or deep in GitHub itself. I’ve finally compiled over 7,000 repositories into a single browsable database. 🌐 Check it out here: The Internet Cafe It’s organized in a Notion-style format, categorized and searchable. I'm planning to keep updating and improving it over time, possibly adding filters, tags, and maybe an API if there's demand. 🧠 Why I built it: I wanted a personal archive of inspiring open-source projects. Hacker News has gems that disappear after a day. I figured others might benefit from the same archive. 📣 I’d love to hear your feedback — whether it’s about the format, usefulness, or features you'd like to see added. Let me know what you think — and feel free to share it if you think others might find it useful. Cheers!  ( 3 min )

Slow queries can quietly erode performance, which frustrates users and strains your system. Fortunately, MySQL offers EXPLAIN, a diagnostic tool that reveals how your queries execute. Think of it as a window into your database engine’s decision-making process. With EXPLAIN, you can figure out exactly why a query is underperforming. Maybe it’s looking at too many rows, ignoring indexes, or struggling with joins. This understanding is key for developers and database administrators who are aiming to optimize performance. To use EXPLAIN, simply place it before your query. It works with SELECT, INSERT, UPDATE, or DELETE statements. For instance: EXPLAIN SELECT name, email FROM customers WHERE age > 30; This will return the query execution plan in table format. +----+-------------+-----------+…  ( 8 min )

Introduction When working with Jest in a TypeScript environment, particularly with mocked functions, you may encounter issues where one test affects another. This problem often arises when mocking is not properly reset, leading to test interference. In this article, we’ll explore why this side effect occurs and provide you with effective solutions, especially in your example involving test cases for the loginPagePresenter. Understanding the Side Effect In your case, the issue stems from the way Jest mocks the apiGateway.post function.

Jest mocks maintain their state across tests unless specified otherwise. This can lead to unexpected results, especially in scen…  ( 4 min )

The common approach to using sprite sheets involves applying CSS classes with pre-calculated coordinates to control the positioning within the sheet. This typically relies on background-image, which does not natively support features like alt text or lazy loading that come built-in with elements. Additionally, using can improve accessibility and semantics depending on how the image is used. This approach builds upon an article on css-tricks, and expands it by introducing scaling of the individual sprites. Skip to Codepen Demo object-fit: none and object-position: x y allow us to select specific areas of an image which is the basis of this idea. The object-position values need to be pre-calculated, just like in the class-based approach. This could be stored as an object literal…  ( 5 min )

For a SaaS (Software as a Service) product, choosing between MySQL and MongoDB depends heavily on the type of data, scalability needs, and how the app works. Use Case Recommendation Traditional SaaS (multi-tenant, structured data, relational) ✅ MySQL Flexible, unstructured, dynamic data (e.g., user-generated content, document-heavy) ✅ MongoDB Feature MySQL (Relational) MongoDB (NoSQL Document) Data Structure Tables, Rows, Foreign Keys (SQL) JSON-like Documents (BSON) Schema Fixed schema (strong structure) Schema-less (flexible) Joins & Relationships Native support Complex joins are harder Transactions Strong ACID support ACID (limited or requires special setup) Scalability Vertical + Read replicas Easily horizontally scalable Performance Great for complex queries, joins Fast for large, flexible datasets Multi-Tenancy Support Very strong (tenant per row, schema, DB) Requires thoughtful design MySQL: SaaS with complex relational data (users, roles, payments, subscriptions). Requires data integrity and transactions (e.g., financial systems). Example: B2B CRM, ERP, Invoicing software. Strong multi-tenant support using shared schema with tenant_id. MongoDB: SaaS with highly dynamic or nested data, like CMS or analytics dashboards. You don’t rely heavily on relationships or joins. You need to store flexible documents per user. Faster iterations and schema evolution. SaaS Type Best DB Project Management Tool (tasks, users, teams) ✅ MySQL CMS/Blog Platform ✅ MongoDB Analytics or IoT Dashboard ✅ MongoDB Accounting / Billing SaaS ✅ MySQL Chat/Messaging SaaS ✅ MongoDB (with Redis/Cache) Some large SaaS companies use both: MySQL for core user/accounts/transactions. MongoDB or ElasticSearch for logs, analytics, unstructured content. If you are: Building a structured SaaS with users, payments, plans, etc. → go with MySQL Building a dynamic content-based platform or analytics service → go with MongoDB  ( 3 min )

As an IAM SaaS company, our work often remains in the shadows—until something goes wrong. Today, I want to shed light on how we handle security at the very first layer all IAM systems have: the login page. Specifically, I’ll walk you through an incident we managed at Cloud-IAM, where we provide a managed Keycloak solution, and share some insights on securing authentication systems against evolving enumeration attack threats. Many of our clients are tech enthusiasts and small companies that want to avoid the complexity of configuring and maintaining Keycloak. Our larger clients, on the other hand, demand resilience. However, resilience is often measured in terms of Monthly Active Users (MAUs), without fully considering the exposure of their service. For example, take two hypothetical compa…  ( 6 min )

When working with JWT authentication in C#, you might encounter a common issue: the token signature validation fails due to a missing 'kid' (Key ID) in the header. This issue often surfaces when using the HS256 algorithm without a kid component, particularly when your token is validated against a set of keys that do not match. Understanding JWT Tokens and Signature Validation JWT (JSON Web Token) is a widely used token format for secure communication between parties. A JWT typically consists of three parts: header, payload, and signature. The header contains information about how the token is signed, including its algorithm and, optionally, a 'kid' if multiple signing keys are involved. In situations where the 'kid' is missing, the application may not be able to match the signing key prope…  ( 4 min )

“Europe’s new space telescope will create a 3D map of the cosmos to explore the effects of dark energy.”– Korey Haynes In one of my earlier blogs, we spoke about the James Webb Space Telescope and how it is changing our understanding of the universe.

Elm is renowned for its commitment to reliability and predictability in web applications. One of the key design decisions behind Elm’s success is its strict enforcement of managed side effects. Unlike many other languages where developers can introduce side effects at will, Elm mandates that all interactions with the outside world be handled only through its controlled mechanisms. This deliberate choice helps maintain purity, consistency, and overall code health. In this post, we’ll explore: What side effects are and why arbitrary side effects can be problematic. The advantages of Elm’s enforced, managed approach. How Elm implements this design with Commands (Cmd) and Subscriptions (Sub). Real-world scenarios that benefit from this disciplined strategy.

“An icy visitor flames out in dramatic fashion”– Sean Walker A comet is a small icy object that orbits the Sun. It’s made of dust, rock, and frozen gases (like water ice, carbon dioxide, and more). I’m sure that everyone’s familiar with this definition of a comet, but today we’re not talking about comets in general but a specific one — ATLAS! Comet ATLAS or C/2024 G3 was named after ATLAS- Asteroid Terrestrial-impact Last Alert System, which was the first to discover it. Comet ATLAS was a 19th-magnitude object. To explain, the magnitude of an object measures its brightness. The brighter the object the lower the number. The comet is also described as having a diffuse coma and a short tail. A coma is a cloud of gas and dust that forms around the nucleus of a comet upon receiving heat from th…  ( 4 min )

In Java, file reading and writing can be done efficiently using buffered streams, readers, and writers. Here's a short explanation with examples: 1. Buffered File Reading (Using BufferedReader) Buffers data for efficient reading (instead of byte-by-byte). import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; public class ReadFile { public static void main(String[] args) { try (BufferedReader reader = new BufferedReader(new FileReader("file.txt"))) { String line; while ((line = reader.readLine()) != null) { // Reads line-by-line System.out.println(line); } } catch (IOException e) { e.printStackTrace(); } } } 2. Buffered File Writing (Using BufferedWriter) Buffers data for efficient writing. import java.io.BufferedWriter; import java.io.FileWriter; import java.io.IOException; public class WriteFile { public static void main(String[] args) { try (BufferedWriter writer = new BufferedWriter(new FileWriter("output.txt"))) { writer.write("Hello, Java!"); writer.newLine(); // Adds a newline } catch (IOException e) { e.printStackTrace(); } } } 3. Key Classes Class Purpose FileReader / FileWriter Reads/Writes characters (text files). BufferedReader / BufferedWriter Wraps readers/writers for buffered I/O. FileInputStream / FileOutputStream Reads/Writes bytes (binary files). Scanner Alternative for reading text (e.g., new Scanner(new File("file.txt"))). 4. Try-with-Resources Automatically closes files (no need for finally blocks). Used in the examples above (try (BufferedReader ...)). When to Use? Use BufferedReader/BufferedWriter for text files. Use FileInputStream/FileOutputStream for binary files (images, etc.). Use Scanner for parsing structured text. Let me know if you'd like a deeper explanation! 🚀  ( 3 min )

✅ Understanding the Goal You're being asked to implement a function called deepEqual(valueA, valueB) that checks if two values (which can be primitives, objects, or arrays) are deeply equal. The keyword here is deep, this means we can’t just check equality on the surface (like ===), especially for things like objects and arrays. We need to go into nested levels and check if all elements or properties match recursively. 🧠 Think Like This, Before you jump into code, ask yourself questions like: -> What types of values can valueA and valueB be? -> How do I handle primitive types vs arrays vs objects? -> What does it mean for arrays or objects to be “equal”? -> Should I use recursion? 🤔Design Your Thinking Strategy: Base case: If a === b, return true. Type check: If types differ, return false. If both are arrays: Check length. Recursively compare each element. If both are objects (but not arrays): Compare keys. Recursively compare each corresponding value. Otherwise: return false. 🔁 Why Recursion? Why Loops Alone Aren’t Enough? A simple for loop works great when you're comparing flat structures, like two arrays of numbers. But when the data can go many levels deep , arrays inside objects inside arrays, etc. you’d need: a loop inside a loop inside a loop... 😵 or a smarter approach that can handle any depth That’s Where Recursion Shines. Recursion is perfect for tree-like or nested structures, because you can say: “If the current level is an array or object, go deeper and run the same logic again.” So your function ends up being clean and adaptable to any depth. ⚡️Implementation of the deepEqual function using recursion: With a clear understanding of recursion and careful handling of data types, you now have a robust deepEqual function that can accurately compare even the most nested structures, a must-have tool in any JavaScript developer's toolkit.  ( 3 min )

At first glance, an ID might seem like the most boring part of your application. It's just a unique identifier, right? But if you're building systems that scale - across regions, across teams, across microservices - your ID generation strategy can be the silent hero or the hidden landmine. And that’s exactly why companies like Netflix, Twitter, Stripe, and Shopify have ditched traditional auto-incrementing IDs in favor of UUIDs and Snowflake-like systems. Let’s explore why UUIDs are not just random gibberish, but a critical architectural decision in high-scale systems - and what lessons we can steal from the giants. Auto-incrementing integers are deceptively simple and convenient. They work great when: You have a single database. You can guarantee a single source of truth. You're not worri…  ( 5 min )

When reading discussions about C++ variable definitions and their associated rules, it’s essential to understand the distinctions between variable definition, initialization, and assignment. Each concept plays a crucial role in how variables behave within C++ code, and knowing these differences can significantly enhance your programming efficiency. Let's delve deeper into variables in C++ and clarify these terms with examples. Understanding Variable Definition In C++, variable definition is the process of declaring a variable to let the compiler know the variable’s type and its name. For instance: int x; // Variable definition Here, int x; tells the compiler to reserve space in memory for an integer variable named x. However, at this point, x does not hold any value; it’s simply defined. …  ( 5 min )

Google is testing a new “Desktop View” mode in Android — and it’s more than just screen mirroring. We’re talking about taskbars, resizable windows, mouse support, and full-on multitasking. Basically, a PC layout powered by your phone. If this rolls out, it could mean you won’t need a Samsung device to get that DeX-style desktop experience. Hidden taskbar (like Windows or ChromeOS) Drag-and-drop between apps Resizable, windowed apps Smooth support for external monitors Mouse + keyboard ready It’s currently tucked away in Android beta builds, but signs suggest Google is moving fast with this. Samsung DeX gave us a glimpse of mobile desktop computing. But now Google is building something native — possibly for all Android phones. That means more freedom for users, especially those who want to work on the go with just a phone and a screen. This could shift how we think about smartphones in workspaces.

Imagine you're trying to teach a child how to recognize fruits. You show them dozens of apples, bananas, and oranges, telling them the name of each fruit. Over time, the child learns to distinguish between them, even when they see new fruits for the first time. This, in a way, is what Machine Learning (ML) is all about—teaching machines to learn from data and make decisions or predictions without being explicitly programmed. 🧠 So, What Is Machine Learning? At its core, Machine Learning is the art and science of solving problems by learning from data. We start with a problem, gather data related to it, and then use algorithms to build a statistical model that can make sense of new, unseen data. But ML isn’t one-size-fits-all.

Introduction Traditional perimeter-based security models are no longer adequate to protect against today's sophisticated and evolving cyber threats. The Zero Trust Security Model offers a fundamental shift: trust no one—inside or outside the network—by default. Zero Trust enforces the principle of least privilege access, evaluating every access request individually. Unlike the traditional "castle-and-moat" model, Zero Trust assumes perpetual network exposure and ensures granular control over who can access what. Remote Work Expansion: Employees now access corporate resources from multiple devices and locations, dissolving traditional boundaries. Cloud Adoption: With workloads moving to the cloud, network-based access control is ineffective. Internal Threats: Trusting internal users witho…  ( 4 min )

In the vast world of computer science, while the foundations and principles of algorithms remain consistent, the ways we approach, implement, and analyze them continue to evolve. Today, we’ll delve into a distinct implementation of the insertion sort algorithm and an innovative tool that simplifies its analysis, both brought to the fore by Fernando Pelliccioni. The provided algorithm, while rooted in the classic insertion sort paradigm, offers a twist — working its magic backward: `function insertion_sort_backward(f, l, r) { } function linear_insert_backward(c, l, r) { var s = sequence(array_descending(), "s", lt); print(s); Understanding an algorithm is one thing; seeing it in action is another. Fernando Pelliccioni introduces an insightful GUI tool for this very purpose: componentsprogramming.com/algorithms. This interactive platform not only animates the algorithm’s execution but also serves insights into memory sequences, variables, stack calls, and various operation statistics. A glimpse into the potential data output: n: 10 (Note: The above metrics are illustrative and may not reflect the actual values for specific runs.) While the foundational algorithms might be familiar territory, it’s the nuanced implementations and tools for deeper understanding that elevate our coding journeys. Fernando Pelliccioni’s distinct implementation of the insertion sort and the accompanying analysis tool stand as testaments to innovation in the world of algorithms. Whether you’re a programming veteran or a newcomer, the landscape of algorithms always promises fresh terrains to explore.  ( 4 min )

Introduction In C++, the distinction between friend functions and public member functions is crucial for encapsulation and access control within classes. Both have unique roles when it comes to interacting with class data, yet they serve different purposes and use cases. In this article, we'll explore the differences between friend functions and public functions, clarifying why you might opt for one over the other. Understanding Access Control in C++ Classes C++ employs a strict access control mechanism to ensure data encapsulation. This mechanism encompasses three main categories: public, private, and protected. Public members can be accessed from outside the class, while private members are restricted to the class itself. Protected members, on the other hand, are accessible in derived cl…  ( 5 min )

Introduction This report aims to comprehensively analyze the origins, development history, and controversial position of the Comic Sans font in the design community and among the general public. Comic Sans, as a widely used but controversial font, has become a cultural phenomenon since its release in 1994, sparking extensive discussions about font design, appropriate usage contexts, and readability. Comic Sans was designed by Vincent Connare in 1994 for Microsoft, originally intended to provide a more stylistically appropriate font choice for cartoon character speech bubbles in Microsoft Bob software. Design inspiration came from comic book lettering styles, particularly "The Dark Knight Returns" (lettered by John Costanza) and "Watchmen" (lettered by Dave Gibbons).

Dia 2 - Neurointerfaces — Como nosso cérebro enxerga o Frontend “Don't make me think.” — Steve Krug Essa frase virou um clássico do design de interfaces. E ela tem base neurocientífica: nosso cérebro evita ao máximo o esforço cognitivo desnecessário. Segundo a Teoria do Processamento Dual (Kahneman, 2011), o cérebro humano opera com dois sistemas: Sistema 1: rápido, automático, intuitivo. Sistema 2: lento, deliberado, requer esforço. Sempre que possível, o cérebro usa o Sistema 1 — e só ativa o 2 se for realmente necessário. Isso significa que interfaces que exigem leitura, análise ou adivinhação ativam o sistema mais lento — e geram frustração. Ícones sem legenda (usuário precisa adivinhar) Menus escondidos (hambúrguer, submenus profundos) Mudanças de padrão (ex: botão de "enviar" que parece um ícone) Elementos previsíveis e familiares Legendas claras Hierarquia visual forte Espaço em branco bem utilizado Estudos de eye-tracking (rastreio ocular) mostram que usuários criam um padrão de leitura em F na tela. Isso significa que eles escaneiam de cima para baixo e da esquerda para a direita — e ignoram o resto. Kahneman, D. (2011). Thinking, Fast and Slow. Krug, S. (2014). Don't Make Me Think, Revisited: A Common Sense Approach to Web Usability. Nielsen Norman Group (2006). F-Shaped Pattern For Reading Web Content. Essas obras explicam por que o design intuitivo funciona melhor: ele não força o cérebro a sair do “modo automático”. Reduza a necessidade de pensar. Use padrões comuns da web. Priorize clareza sobre criatividade. Não reinvente botões sem motivo. Dê pistas visuais. Ícones com texto, hierarquia, espaçamento. Teste com usuários reais. Se alguém hesita antes de clicar, sua interface não está clara o suficiente. Criar uma interface clara é um ato de empatia: você está poupando energia mental do seu usuário. Se ele entender o que fazer sem precisar pensar, você venceu. Qual interface você achou mais confusa recentemente? Comenta aqui e vamos analisar no próximo post da série! 👇  ( 4 min )

What if your design system didn't need to ship components in a component library? From an engineering standpoint, most of a design system's maintenance overhead is creating and shipping components for a specific framework coupled to a styling system of some kind. I've been asking the same thing on Medium. And then built a POC to see if it would work and made it available in Github. If using AI agents, component libraries break free of framework and style constraints by generating components at build time from prompts and generator functions. They're still driven by design through tokens and themes, but without prebuilt components. It gets even better when using RAG for distribution and documentation, eliminating tools like Storybook in favor of on-demand generation by AI agents using the system itself, not a collection of stories or API documentation.  ( 3 min )

Hey all, We recently started working on an API Client - Voiden - and wanted to share it here to get your thoughts and feedback. Over the past few years, we found ourselves managing way too many tools just to work with APIs: one for api specs, another for docs, a third for tests, etc etc. Eventually it starts to feel more like a performance than actual work. So we built Voiden: A git-native, extensible, and lightweight client that brings everything—specs, docs, tests, mocks—into one place. No bloat, no lock-in, no "platform overhead." Just structured API workflows that don’t fight your tools or your team. A few things we care about: -Reusability and composability : APIs as building blocks, not silos. -Structure over scatter : everything lives together in one workspace. -No sign-in required : you can use it without creating an account. Free and open — we are building this with the community in mind. Just to be clear: The goal is NOT to replace OpenAPI, but to provide a layer around existing specs that feels coherent, hackable, and friendly to real-world dev workflows. You can check it out here: https://voiden.md/ And if you have feedback, suggestions, or just want to follow along: https://github.com/VoidenHQ/feedback We are still early, but would love to hear what you think—what you like, what is missing. Appreciate any time you take to try it out. Nikolas  ( 3 min )

Introduction Can we store polymorphic objects by value in C++ STL containers? This topic often arises among C++ developers, particularly with the challenges posed by object slicing when dealing with base and derived classes. The crux of the issue lies in the behavior of STL containers and how they handle objects. In C++, when we store derived class instances in a container that holds base class objects by value, object slicing occurs, which results in the loss of the derived class-specific behaviour. This article aims to explore this concept specifically within the context of C++11 and later revisions, dissecting the challenges and potential approaches. Understanding the Slicing Problem When you store a derived class object in a container designed to hold objects of its base class by value…  ( 5 min )

Building resilient, production-grade workflows means preparing for the unexpected—from task stalls to external service outages. While task-level timeouts catch issues in isolated steps, workflow-level resilience settings act as a safety net for your entire orchestration. They ensure your system behaves predictably under stress and provides a graceful fallback when things go wrong. In this post, we’ll explore two key features in Orkes Conductor that help you build robust workflows: Workflow Timeouts Failure Workflows (a.k.a. Compensation flows) A workflow timeout defines how long a workflow is allowed to run before it's forcibly marked as timed out. This is crucial when your business logic needs to meet service-level agreements (SLAs) or avoid workflows stalling indefinitely. Workflow timeo…  ( 6 min )

Imagining AI Companions as Conversationalists in 2025 The evolution of artificial intelligence is impressive. Sitting here in 2025, AI chat companions are capable of conversation in ways we never thought would be possible. No longer are these digital companions simple conversationalists who follow a script; now, they can communicate with understanding of context and emotion through any form of dialogue—academic or sexual. Consider yesterday's scenario. Once upon a time, chat functionality existed in simple programs that fell apart if the user strayed even slightly from the predetermined prompt. But that's not the case in 2025. Today's counterparts exist in a world far removed from yesterday's failed experiments. With context-cued language models trained on billions of conversations, thes…  ( 6 min )

🔐 Temporary credentials in AWS are powerful—but also widely misunderstood. They allow developers and systems to access AWS resources without relying on long-lived access keys. But just because they expire doesn’t mean they’re safe by default. In this post, I break down: ✅ When and why to use temporary credentials 🧱 Where things go wrong (over-permissive roles, lazy session durations…) 🔒 Best practices for keeping temp creds secure 🧠 Advanced use cases like federation and IAM Roles Anywhere I’ve seen real-world setups where: Temp credentials lasted 12 hours Were used with AdministratorAccess In CI/CD pipelines with no monitoring That defeats the whole point of ephemeral access. Should Be Doing 🔸 Use least privilege roles Scope your roles tightly and use IAM condition keys like aws:SourceIp. 🔸 Shorten session durations 15–30 minutes is more than enough for most automation tasks. 🔸 Log STS usage with CloudTrail Every AssumeRole or GetSessionToken should be traceable and alertable. 🔸 Require MFA where appropriate Especially for sensitive role assumptions—break-glass or prod access. 🔸 Automate responsibly Don’t reuse temporary creds or store them insecurely in config files. Use the SDKs properly. For non-AWS workloads (like on-prem apps), IAM Roles Anywhere lets you issue short-lived AWS credentials using signed certificates. It's a powerful addition for hybrid setups, but comes with its own set of guardrails. The original article goes deeper into: Federation setups with Okta or AzureAD Example real-world misuses (and fixes) Credential rotation strategies 👉 Read the full guide here Let me know: How is your team managing AWS access today?

When diving into the Swift language, especially for those new to the community, understanding how the Swift compiler treats opaque type declarations can be confusing. In your example, you're encountering a common scenario that many developers face when dealing with opaque types in Swift. Let's clarify this by breaking down your code and explaining why the behavior you're seeing is occurring. Understanding Opaque Types in Swift Swift's opaque types, introduced with the some keyword, allow developers to specify that a function will return a value conforming to a specific protocol without revealing its exact type. This is particularly useful for abstracting away implementation details while still adhering to protocols. In your code: protocol Animal {} class Dog: Animal {} func getMeADog() -…  ( 5 min )

At its core, FTP is a standard network protocol used to transfer files between a client and a remote server. Introduced in the early days of the internet, it was originally designed to simplify data sharing across ARPANET. Today, its primary use remains the same—allowing users to upload, download, and manage files between devices and systems across networks. While web browsers offer limited FTP support, professionals often turn to dedicated tools like FileZilla and Cyberduck to handle more advanced workflows. An FTP session typically initiates two connections: Control Channel: Handles command exchange and session setup. Data Channel: Transfers the actual file content. This dual-channel approach allows FTP to streamline complex file operations, enabling simultaneous uploads and downloads wi…  ( 4 min )

Beyond Small Talk: How AI Chatbots Surpassed the Uncanny Valley by 2025 Remember when chatting with AI was like talking to a glorified calculator with some sarcastic punchlines? Such memories are quickly becoming a thing of the past, though. By 2025, chat-based communication with AI has reached such great heights that it's practically comparable to human communication in certain unexpected realms. The shift from having simple first-chatbots to playing with AI to now conversing with it fully is one of the most impressive developments in contemporary computing.

The Mechanics of Humanization But how is this happening? Are all these people really transferring from talking to humans to talking to machines? What does the language model operate behind these AIs? In 2025, there is no ambiguity between talking and chat bots. It's framed mostly by instruction and subsequently, output. Of course, the ability for AI to talk like a human wasn't developed overnight either. Over the years, developments in large language processing models have created systems that operate on trillions of parameters - whereas previous iterations operated on mere billions. This difference of magnitude means that AI can better understand context, remember previous messages and conversations, and stay on task within one stream of consciousness across lengthier periods.

Structured Query Language (SQL) is an essential tool for working with databases, but even seasoned developers sometimes make mistakes that can lead to slow queries, inaccurate data, and inefficient systems. When summarizing data, the GROUP BY clause organizes information into meaningful groups. However, misusing GROUP BY can lead to incorrect results—sometimes without obvious errors. A database tracks employee salaries per department. Someone writes: sql To summarize salaries by department, the query should be: sql sql Only group necessary columns—non-grouped columns need aggregate functions. Use HAVING instead of WHERE for filtering grouped results: sql During testing, SELECT * is quick and handy. But in production? It slows queries, overloads networks, and makes applications harder to maintain. sql sql Explicitly specify needed columns instead of SELECT *. Use LIMIT for large queries: sql sql sql Indexes speed up data retrieval, but poorly designed indexes can slow down updates, inserts, and deletes. sql A better strategy: sql Index columns frequently used in WHERE clauses. Avoid over-indexing, which slows write operations. Use EXPLAIN or ANALYZE to check query performance: sql Use composite indexes only when queries filter by multiple columns: sql NULL values represent missing information, and if not handled correctly, they can cause errors or misleading results. This query calculates average salaries: sql Ensure NULLs are accounted for: sql sql Use IS NULL and IS NOT NULL to prevent logic errors. Replace NULLs using COALESCE() or IFNULL(): sql Validate NULL handling in reports to avoid misleading calculations. SQL mistakes can affect speed, accuracy, and system stability. But with the right practices, you can write efficient, optimized queries that scale well. GROUP BY must include all non-aggregated columns to avoid incorrect grouping. Never use SELECT * in production—fetch only required data. Index smartly, targeting commonly searched fields. Handle NULLs carefully, ensuring accurate calculations.  ( 4 min )

If you're building coding agents or automated developer workflows, you'll quickly discover the challenge of finding a robust, non-interactive CLI tool for code generation and modification. While human-in-the-loop coding (where a developer guides the AI) is still the gold standard for complex software, there's a growing need for tools that can operate fully autonomously—especially for simple, repetitive tasks or as part of larger agentic systems. I'm working on building an AI agent for creating playable ads—essentially mini games that can be used as interactive advertisements.

When I first thought about switching from Windows to Linux, the main reason was simple — I want to control my computer. ⚙️ I love to automate everything One of the main reasons I chose Linux is the ability to automate everything. Every update, every new package — I decide what and how to install. This isn’t tied to forced downloads like in Windows. This is my freedom. 🌍 A world of options Linux gives you a huge variety of distributions, each suited to different needs. It’s like a builder where you choose what you need: I started with Ubuntu, because it’s stable, user-friendly, and has good documentation. But now I’m getting more interested in Arch and Fedora. I’ve realized that in Linux, it’s easy to switch between distributions, migrate between them, and adapt the system to your needs. 💻 Tech and CTF My passion for CTF and cybersecurity gave me even more reasons to switch to Linux. This system provides me with the tools to work with security, set up virtual machines, create test environments, and perform various attacks. You can’t achieve that in Windows, not to the same extent. Linux is a system for people who not only want to use technology but also understand it from the inside. For me, it’s not just an operating system, it’s a tool for growth and self-expression. 🌟 My freedom After switching to Linux, I felt that I was finally in control of my system. It’s not just an OS, it’s an environment that allows me to build, optimize, and use my computer the way I need. 🚀 Final thoughts If you’re tired of your computer not being yours, try Linux. A system where you decide how everything works. Where you can customize everything, automate it, and learn. It doesn’t matter if you’re a beginner or an experienced user — Linux has something for everyone.

Summary WhatsApp imposes a 24-hour customer-service window during which you can send any message; outside of it, only template messages (unformatted) are allowed. Goalmatic.io needs to let users send richly formatted content (articles, poems, etc.), so we built a two-step workaround: Template Send: Strip formatting and send via a WhatsApp template. On-Click Upgrade: Include a “Get Formatted Text” button in the template. When the user clicks, the 24-hour window reopens, allowing us to send the original, fully formatted message. Below is an end-to-end example in Node.js using the WhatsApp Cloud API. WhatsApp’s customer-service window rules mean: Within 24 hours of a user message, you can send any content (text, media, formatted).

We will focus specifically on how to ensure that errors thrown from your view model can be gracefully handled at the view level. Understanding the Issue In Swift applications, especially those using SwiftUI, it can sometimes occur that errors that are thrown from a view model do not propagate to the view layer. This can lead to confusion as you may not see the expected error messages in your user interface. In your case, while the error logging from the network layer indicates that an error is being produced, the error isn't…  ( 5 min )

When developing web applications, storing data in the browser is essential for maintaining user sessions, saving preferences, and improving performance. Three common methods for client-side storage are Local Storage, Session Storage, and Cookies. While they serve similar purposes, they differ in data persistence, size limits, and accessibility. This article will explore the differences, advantages, and best use cases for each storage method. Local Storage is a browser-based storage mechanism that allows web applications to store key-value data persistently on the user’s device. The stored data does not expire and remains available even after users close and reopen the browser. ✔️ Persistent Data — Data is stored permanently until manually deleted // Storing data in Local Storage localStora…  ( 5 min )

Hey Devs! 👋 Yeah, I know… it’s been a while 😅 LearningTrackApp (name still under construction 😅) So this new app I’m building is a platform made for NGOs — specifically the ones that teach underprivileged kids. The idea is to help them keep track of their students’ progress, batch sessions, timings, names — basically everything important in one place. It’s simple, but I think it’s gonna be really useful. The app has a few different roles to keep everything organized: Super Admin – can access and manage all the NGOs. Admin – manages just their own NGO. Supervisor – the on-site person ensuring sessions are running smoothly. Volunteers – the awesome people who teach the kids. Students – well, this one explains itself 😄 That’s pretty much what I wanted to share for now. I genuinely feel like this app can be something impactful, and I’m excited to build it step by step.

Writing clean SQL is about more than just correctness—it's about clarity. SQL comments help you communicate with others (or your future self) by adding context, notes, or temporarily disabling code. Let’s explore how to use comments effectively. Using Comments in SQL Two Main Types: Single-line -- Pull users created in the last week SELECT * FROM users WHERE created_at >= CURRENT_DATE - INTERVAL '7 days'; Multi-line /* Use this version for reporting Includes only verified accounts */ SELECT * FROM accounts WHERE verified = TRUE; Why and When to Comment Helpful When: Writing complex logic Sharing scripts with a team Disabling old queries during testing Avoid: Leaving sensitive info Explaining simple queries Letting comments go stale Different Engines, Different Capabilities MySQL: Supports versioned comments /*! */. PostgreSQL: COMMENT ON lets you label schema elements. SQLite: Keeps it basic and portable. SQL Server & Oracle: Great for documenting stored code and schema. FAQ How do I add comments in SQL? Use -- for quick notes or /* */ for multiple lines or blocks. Yes—wrap code in /* */ and it won’t run. Yes, both styles are widely supported with small engine-specific features. Only if they include secrets or mislead developers. Keep them clean and relevant. Conclusion SQL comments don’t take much effort but make a big difference.

Let’s walk through some practical tips and real Go examples to help you write cleaner and more idiomatic code. Don’t try to be clever. Clarity beats brevity every time. ❌ Bad: func f(u int) { fmt.Println(u) } ✅ Good: func printUserID(userID int) { fmt.Println(userID) } Use camelCase for variables and functions. Reserve abbreviations for widely recognized terms like id, url, db. One function = one responsibility. Break up logic when possible. ❌ Bad: func h…  ( 5 min )

In Python programming, it's common to define constants that are used throughout your code. These constants, stored in a file like constants.py, can help keep your code organized and make it easier to update settings or values in the future. However, when documenting functions that use these constants, developers often face the dilemma of whether to refer to the constants directly in the documentation or use their values instead. Why Use Constants in Python? Constants like PATH_DATASETS = "data/datasets/" and WIDTH = 416 serve as fixed values that can be reused across multiple functions in your program. This practice enhances code readability, maintainability, and minimizes the risk of introducing errors when changes are needed. The Problem with Documentation When you define a function that…  ( 5 min )

The Hook: Remember When Investing Meant Picking Stocks Based on Your Gut I still recall my initial portfolio-building effort. It was 2011. I purchased a few tech stocks because, you know, "tech is the future," right? I did my research by spending two hours on Reddit and a tip from a colleague who once read The Intelligent Investor. Of course, I lost money. Flash-forward to the present day, and we're in a whole different galaxy. You no longer need a finance degree or a Bloomberg terminal. You just need an app—driven by AI. Artificial intelligence is not only upending finance—it's changing the way portfolios are constructed, managed, and optimized.

One of the key challenges I have found with the built in Power Platform Pipelines is that it doesn't cover connections. The expectation is that the developer will deploy to production through a spn (as we don't want them to have access to edit production), but the new flows use the developers connections, wait what. The 2 benefits of ALM are: Cant access prod If they leave still works Well with this setup the developer still needs access to the prod data source, and if they leave it breaks. Fortunately there is a way, well actually 2. Matt Collins-Jones found the best way and documented it brilliantly at https://www.mattcollinsjones.co.uk/single-post/change-connections-during-deployments-power-platform-pipelines, I highly recommend reading it My way is a lot less graceful, but has the on…  ( 6 min )

What if I told you that building large, feature-packed mobile apps is no longer the smartest move? We're entering an era where micro-apps — small, self-contained, purpose-driven applications — are transforming how we build and scale mobile experiences. And if you're not exploring them yet, you're already behind. A micro-app is a lightweight, independent application designed to handle a specific task or feature. Think of it as a “microservice,” but for the frontend of mobile apps. They're typically: Built independently from the main app Focused on one specific use-case (e.g., payment, chat, onboarding) Easily deployable without affecting the entire app Written in a variety of frameworks or stacks Instead of one monolithic app that tries to do everything, you create multiple micro-…  ( 5 min )

👋 Hello Dev Community — From Guyana with Love! Hey everyone! I'm Nathaniel, a developer and computer science student from Guyana — a small country on the South American mainland. I’m passionate about writing clean code, building full-stack applications, and diving deep into topics like JWTs, web architecture, and system-level programming in C. But beyond that, I’m also deeply interested in how technology is growing (or struggling) in Guyana — from internet access to education to the startup scene. To share dev articles and tutorials, especially things I’ve learned or struggled with as a student and builder. To spotlight Guyana’s tech space, which I think deserves more global attention and internal discussion. To connect with other developers, both in the Caribbean and internationally, and learn from their stories as well. I’ve noticed there's not a lot of content on Dev.to about tech in Guyana, so I want to help change that. Whether you’re here for tutorials, dev opinions, or insights into building a tech career from a small country, I hope my posts can add value. Feel free to reach out, share your thoughts, or even suggest topics you'd like to see discussed.  ( 3 min )

In TypeScript, creating generic functions can significantly increase your code's reusability and type safety. One common requirement is to extract keys from a given type, ensuring that your functions handle different types effectively. In this article, we will focus on how to implement the get_keys() function, which retrieves the keys of a specified type T. Understanding the Requirement The get_keys() function is designed to return the keys of any given type T. This function will be helpful when you want to dynamically work with the properties of objects or interfaces defined in TypeScript, especially when you are dealing with complex data structures. By doing so, you can create a more dynamic and type-safe codebase. Why Use TypeScript's Generics? Generics in TypeScript allow you to …  ( 5 min )

I originally posted this post on my blog. I didn't pay for the most expensive hamburgers I've eaten. An ex-employer did. When I say "most expensive," I mean the same greasy $5 or $10-dollar hamburger from a food truck or a corner in a busy street. But they felt expensive because I ate them while working overnight. In a past job, when my team was lagging behind the self-imposed deadlines of sprints, higher-ups told us: "This sprint is behind schedule. What are you going to do? You're a self-managed team, so decide that by yourselves. But if I were you, I'd choose to work overtime to keep up." "You're a self-managed team" was their subtle way of telling us to work extra hours, without accepting any responsibility. We didn't have any say in what tasks to do and how. We were only a self-managed team when it came to choosing to work overtime. They didn't pay us for that extra time. They only bought us hamburgers. And, when someone raised their concerns about the quality of those hamburgers, they told us we should be grateful because other companies buy their employees nothing to eat. If you're told you're part of a self-managed team, read the fine print. Look for signs of real self-managed teams: Look at job descriptions. Connect with people already working there. Ask follow-up questions during interviews. Otherwise, they might expect you to work overtime without compensation or just buy you an hamburger.

When optimizing Angular applications for performance, developers often overlook a silent culprit: TypeScript enums. While enums improve code readability and type safety, they introduce unexpected overhead in your final JavaScript bundle. This can lead to larger file sizes, slower load times, and diminished performance, especially on mobile or low-bandwidth connections. In this article, we'll explore how enums contribute to bundle bloat, why Angular's build tools struggle to optimize them, and which alternatives you can use to write cleaner, faster, and more efficient code. An enum is a TypeScript feature that lets you define a set of named constants. For example: export enum UserRole { Admin, Editor, Viewer } Under the hood, this compiles to something like: "use strict"; var UserRo…  ( 5 min )

🧩 Implementation: @Injectable() export class DestroyService extends Subject { ngOnDestroy() { this.next(); this.complete(); } } 🧩 Question: ngOnDestroy() in this pattern? Even though DestroyService is a service and extends Subject, how does Angular still invoke ngOnDestroy()? 💡 Answer: Even though DestroyService extends Subject (which is not a component or directive), Angular still calls its ngOnDestroy() method if the service is provided at the component level. 🔑 Why ngOnDestroy() Gets Called in a Service ✅ Angular will call ngOnDestroy() if: The class implements OnDestroy AND it is a provider on a component or directive Example: @Component({ Then Angular treats the service like a directive-level provider, and because it has ngOnDestroy(): 🧠 Why It Works Even Though It Extends Subject Subject has no ngOnDestroy(). That's fine. You're extending Subject and adding ngOnDestroy() yourself. Angular doesn’t care that it extends Subject — it just sees: “This class was provided in the component” “It has ngOnDestroy()” ✅ Call it when the component is destroyed 🔁 Summary DestroyService is a service, but it's scoped to the component using providers: [DestroyService] It has a custom ngOnDestroy() method Angular calls ngOnDestroy() on component-scoped providers So you get an automatic, injectable "destroy notifier" for use with takeUntil() This is a neat Angular trick that combines: Lifecycle hooks Dependency injection RxJS into a reusable, composable unsubscribe mechanism.

The CSS Box Model is one of the most important concepts in web design 🧱. It describes how elements are structured on a webpage — every HTML element is treated like a box with layers: content, padding, border, and margin. 💡 What I Made I created a simple webpage using HTML and CSS ✨. It shows a box with the message "Hello Kts". You can view the live demo here: The design is simple but effective — a colored box with space inside and outside, and a border to highlight the shape. 🧠 How the Box Model Works in My Project: Margin: It adds space outside the box (like a buffer from the edges) ➡️ Padding: It adds space inside the box around the text, making it look neat 🧍‍♂️ Border: This creates a clear outline around the box ⚫ Background color: I used a brown background to make the box stand out 🟤 🚀 Why It Matters?

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: That's Entertainment! I built a text adventure game inspired by the history of ancient Pompeii. I believe my text adventure game differentiates itself by adding new features to the UI as you progress through the game.

In this article, we will explore why Go allows type comparisons that might initially seem surprising, particularly in instances like comparing an integer to a string. We'll explain the underlying mechanisms of Go's type system and how the language handles such comparisons without raising errors or panics. Understanding Go's Type System Go is a statically typed language, which means that the types of all variables are known at compile time. When you define a variable, its type must be explicitly declared or inferred, leading to a robust type safety framework. However, Go introduces a unique feature with the any type, which can hold a value of any type. This flexibility plays a crucial role in our example. The Role of the any Type In your provided code, we see the variable hello is declared …  ( 5 min )

In the competitive world of e-commerce, monitoring prices on platforms like Amazon is crucial for businesses and savvy shoppers alike. However, scraping data directly from such websites can lead to IP bans and access restrictions. To mitigate these risks, using Python in conjunction with proxy IPs offers a safe and effective solution for price monitoring. Why Use Proxies for Amazon Price Monitoring? Anonymity: Proxies mask your real IP address, making it difficult for websites to track your scraping activities. import requests proxy = { http://your_proxy_ip:port", http://your_proxy_ip:port" def get_price(url): # Find the price element (this may vary based on the product page) url = 'https://www.amazon.com/dp/your_product_id' Static and Residential IPs: These are less likely to be flagged by Amazon.

连续分享了几天的Uniapp跨平台开发鸿蒙应用教程的文章，相信大家对跨平台开发已经有了初步的了解，今天分享一下跨平台开发中的自定义导航栏。 在Hbuilder的初始化项目中是自带了导航栏的，这是一个全局的导航栏，它的样式设置和修改是在全局的配置文件pages.json中进行。 现在打开pages.json文件，在globalStyle中有一些关于导航栏的属性，我们尝试修改一下： { "pages": [ //pages数组中第一项表示应用启动页，参考：https://uniapp.dcloud.io/collocation/pages ], "globalStyle": { 然后看到导航栏已经发生了改变： 这样的修改很方便很便捷，但是好像只有颜色和文字这些基础的属性可以修改，很多时候我们需要在导航栏上添加一些组件，比如按钮或者搜索框。 对于这种情况，uniapp也提供了相应的设置方案，还是在pages.json文件中，当我们需要为某一个页面的导航栏添加组件，就在对应的path路径下设置style，style中有个titleNView属性就是为导航栏添加自定义组件，像这样： "path": "pages/index/index", 但是幽蓝君亲测这种设置方式在浏览器运行时可以正常显示，在鸿蒙中是无效的： 所以在鸿蒙开发中我们需要自己定义导航栏。 再次回到pages.json文件，这次将navigationStyle设置成custom，作用是取消原生的导航栏： "path": "pages/index/index", 然后打开需要自定义导航栏的页面，我这里就直接在首页index.vue中操作，实现逻辑比较简单，就是在页面顶部添加一个导航栏大小的组件，然后在其中添加搜索框，相关代码如下： style="width: calc(100% - 40px);background-color: white;height: 35px;padding: 0px 10px;border-radius: 18px;" .custom-nav-bar { / background-color: #f8f8f8; 导航栏背景色 / 其他样式属性 */ 看一下运行效果： 今天就以添加一个搜索框为例，大家如果需要自定义其他的样式也是类似的实现方式。 以上就是uniapp跨平台开发鸿蒙应用中的自定义导航栏，感谢大家的阅读。  ( 3 min )

Most people think hacking is just about tools, code, or some flashy terminal with green text flying by. But that’s not what makes a real hacker. Let me tell you what really matters—the part only 1% truly understand… Forget the tools for a second. Real hacking starts when you ask the questions nobody else is asking: "Why does this work like that?" "What happens if I try something they didn’t expect?" "What’s behind this system they don’t want me to see?" It’s about curiosity. Obsession. Even rebellion. Not following tutorials step-by-step, but breaking patterns and learning how systems truly work under the surface. I’m teaching myself Python and networking— Not because I want to show off, but because I want to understand how the internet and machines actually think. I’m not here to be just another script kiddie. I’m building a foundation. Quietly. Daily. I don’t want fame. I don’t want likes. I want leverage. I want to be the kind of person who sees through the system—and knows how to bend it. A silent weapon. Sharp, skilled, and always learning. Are you learning just to pass exams? Or are you learning to break limits? Be real with yourself. The world’s already full of followers. We need more builders, breakers, and thinkers. If you feel that fire too—the curiosity, the hunger to really understand—drop a comment. Tell me what you're working on. I’m still early in my journey, but I’m in it for real. Let’s learn. Let’s grow. Let’s hack.  ( 3 min )

Creating a visually appealing cladogram can be quite challenging, especially if you're new to coding. It sounds like you want to improve the design aspects of your cladogram, which you initially created on Wikipedia and transferred to Neocities. The good news is that altering the style of your cladogram is achievable with some CSS adjustments. Understanding Cladogram Design Challenges Cladograms often display evolutionary relationships in a tree-like structure, which can look cluttered, particularly when the lines are too short or when the elements aren't properly spaced. Since you mentioned that you initially tried changing the padding but weren't satisfied with the result, let's delve into additional CSS properties that can help enhance the aesthetics of your cladogram. Adjusting CSS Pro…  ( 4 min )

Introdução Com a expansão dos serviços on-line, surge uma demanda cada vez maior por sistemas responsivos, performáticos e de alta capacidade de escalabilidade. O uso da programação assíncrona se mostra muito eficaz na obtenção destes atributos de qualidade durante o desenvolvimento de um software. Este artigo busca mostrar os benefícios e os contrapontos do uso da programação assíncrona em Python em sistemas "I/O-bound" (altamente dependentes de input e output) e outras tarefas que necessitam de execução paralela. Conceitos de programação assíncrona Computadores executam softwares de forma sequencial, isto é, uma instrução após a outra. Um software geralmente realiza múltiplas tarefas, e nem sempre faz sentido esperar que uma tarefa termine antes de iniciar a próxima (SKVORTSOV, 2021). Se…  ( 5 min )

RESUMO Palavras-chave: Arquitetura REST. Sistemas distribuídos. API. HTTP. Serviços Web. 1 INTRODUÇÃO 2 DESENVOLVIMENTO De acordo com Stein Junior (2021), REST surgiu da necessidade de criar interfaces simples e eficientes para a comunicação entre sistemas, principalmente via web. O autor afirma que "o objetivo era criar interfaces simples, escaláveis e independentes, facilitando a comunicação entre sistemas distribuídos por meio do protocolo HTTP" (STEIN JUNIOR, 2021, p. 10). A arquitetura REST é baseada na manipulação de recursos — objetos ou entidades de informação — que são identificados por meio de URIs (Uniform Resource Identifiers) e manipulados utilizando métodos HTTP padronizados, como GET, POST, PUT e DELETE. Fielding (2000) ressalta que uma das principais características do REST…  ( 6 min )

Introduction In the world of numerical computing, transitioning from NumPy to JAX can offer significant performance benefits thanks to JAX's Just-In-Time (JIT) compilation and optimizations for GPU acceleration. However, this transition isn't always smooth for all operations, particularly for those that are heavily transformation-based, such as broadcast_to and moveaxis. In this article, we will explore why these functions may perform slower in JAX compared to NumPy and discuss best practices to optimize their usage. Understanding the Performance Discrepancy Why JAX May Be Slower for Basic Operations The performance of JAX can vary significantly depending on the operations being performed. While JAX is designed for efficient numerical computation and can excel in larger batch sizes and com…  ( 5 min )

Let’s not sugarcoat it—workflow automation should be simple. You sketch out a flow, wire up a few APIs, slap in a trigger, and boom: your job runs itself while you sip coffee. Except… not really. In reality, automation breaks. It misfires. It fails silently. And if you’re building workflows without a plan (I’ve done it), you’ll spend more time debugging than you ever saved. So here are 5 workflow automation mistakes I’ve run into—plus how I fixed them using Martini, a low-code automation platform that somehow gets it. 1. Only Building the Happy Path Raise your hand if you’ve built an automation that worked perfectly—until the first error. I’ve done it. Then I spent the next hour trying to figure out why a webhook timed out and brought down the entire flow. ✅ Fix: Build for failure first.…  ( 4 min )
